Why Choose the Netafim Series 80 Globe Valve

The Series 80 is designed and manufactured by Netafim, the company that pioneered drip irrigation technology and today operates in more than 110 countries. The following points are drawn from the Netafim USA Series 80 product page and the canonical supplier data.

• Glass-reinforced nylon body with full corrosion resistance. The valve body and bonnet are molded from glass-reinforced polyamide (nylon), a material that resists corrosion from fertilizers, chlorinated water, and reclaimed irrigation supplies. Unlike brass or cast-iron valves, nylon does not corrode or leach metals into the water stream—an important consideration in closed-loop hydroponic systems where water quality directly affects plant health. Stainless steel fasteners throughout ensure long service life without galvanic corrosion.
• Integrated flow-control stem for manual flow adjustment. The flow-control stem allows operators to manually set the flow rate anywhere from full closure to the maximum 110 GPM capacity. This is particularly useful in irrigation zones with mixed emitter types or where pressure variation between zones requires hydraulic balancing without adding a separate flow regulator. Adjustment is done in the field without disassembling the valve.
• Quick-reaction opening and closing for high-frequency irrigation cycles. The Series 80 is specifically engineered for quick reaction—rapid opening and closing that suits high-frequency irrigation scheduling common in commercial greenhouse and substrate-culture hydroponic operations. Frequent short irrigation cycles, which keep substrate moisture at optimal levels, require a valve that opens and closes reliably hundreds of times per day without degrading the diaphragm or solenoid.
• Low current draw enables long wire runs from controller to valve. The 0.22 A inrush and 0.095 A holding current ratings are lower than many competing valves. Low current draw means that a single multi-station irrigation controller can drive more valve stations simultaneously, and wire runs between controller and valve can be extended without voltage drop causing false open or close events. This reduces installation cost in large greenhouse or field installations.
• Internal bleed without solenoid removal. The improved manual selector on the Series 80 enables internal bleed—manually opening the valve by bleeding the pressure chamber—without removing the solenoid. This is a practical maintenance feature: operators can test valve operation in the field without tools, without disassembling the valve head, and without the risk of losing solenoid parts in irrigation trenches or grow rooms.
• Integral EasyClean stainless steel filter protects downstream emitters. The 1½ in model includes a built-in stainless steel EasyClean filter at the inlet. This filter catches debris before it reaches micro-irrigation emitters, drip lines, or spray nozzles. The EasyClean design allows the filter screen to be flushed or removed for cleaning without disconnecting the valve from the mainline, reducing maintenance downtime.
• Suitable for reclaimed and reuse water. Netafim certifies the Series 80 as suitable for use with reclaimed water. Commercial operations using reclaimed irrigation water (which may have higher bacterial counts, particulates, and suspended solids than potable water) can use the Series 80 without concern about material degradation from the water quality profile of reclaimed supplies.
• Drip-tight closure for zero-leak zone shutoff. The fully supported Buna-N diaphragm creates a drip-tight seal when the solenoid is de-energized. In multi-zone irrigation systems, leak-free zone isolation prevents unwanted water delivery to inactive zones, which is critical in hydroponic systems where overwatering in one zone can compromise root health and oxygen availability.

Best Uses for the Netafim Series 80 Globe Valve

The use cases below are derived from the valve’s confirmed specifications (flow range 0.25–110 GPM, pressure range 7–150 psi, max temp 140°F) and its category placement in Hydroponic Systems & Water Management > Drip & Irrigation Kits.

• Commercial greenhouse drip irrigation automation. In greenhouse drip systems, the Series 80 globe valve serves as the zone control valve that opens and closes to deliver timed irrigation events to rows of potted plants, grow bags, or substrate-culture trays. The valve’s 0.25–110 GPM flow range accommodates both small-scale greenhouse zones and large-capacity mainlines feeding hundreds of drip emitters simultaneously. Pair with a 1½ in inline filter with 200-mesh screen upstream for additional particle filtration before the valve inlet.
• Hydroponic drip irrigation with precise timing control. Substrate-culture hydroponic systems—coco coir, rockwool slabs, perlite beds—rely on frequent, brief drip events timed by an irrigation controller. The Series 80’s quick-reaction design handles the rapid on-off cycling required by these schedules. The integrated flow control allows the operator to set zone flow independently at the valve, eliminating the need for separate pressure regulators in many installations.
• Mist system control for humidity and evaporative cooling. Greenhouse mist systems for humidity management or evaporative cooling require a valve that opens and closes hundreds of times per day with high reliability. The Series 80’s quick-reaction solenoid and drip-tight diaphragm make it suitable for misting applications where partial opening or slow response would result in uneven humidity distribution or water pooling.
• Climate control and nutrient injection integration. In automated climate control applications—where irrigation events are linked to VPD sensors, temperature readings, or other environmental triggers—the Series 80 provides the actuated valve that responds to controller commands. Its low current draw allows integration with multi-output controllers managing temperature, humidity, lighting, and irrigation from a single panel.
• Open-field precision irrigation for row crops. The 150 psi maximum pressure rating and 110 GPM maximum flow allow the Series 80 to operate on mainlines in open-field drip or micro-sprinkler irrigation layouts, where higher pressures and flow volumes are standard. The nylon body resists UV degradation and the corrosive mineral content common in field irrigation water supplies.
• Reclaimed water irrigation systems. Operations using treated reclaimed water for irrigation—including municipal reclaimed water programs common in water-limited growing regions—can use the Series 80 without compatibility concerns. The nylon body and stainless steel components are rated for reclaimed water use.
• Reverse osmosis system integration. In hydroponic facilities that use a reverse osmosis system for water purification, the Series 80 globe valve can serve as the automated shutoff controlling flow to the RO unit’s feed line or distribution header, enabling timed fill cycles for nutrient mixing tanks.

Netafim Series 80 vs Hunter PGV-151 — Irrigation Globe Valve Comparison

The Hunter PGV-151 is the most direct competing product to the Netafim Series 80 in the 1½ inch globe valve category. Both are 24 VAC electric solenoid globe valves with integrated flow control. The comparison below is based on published technical specifications from each manufacturer.

Netafim Series 80 Globe Valve (this product):

• Pressure range: 20–150 psi (higher minimum operating pressure)
• Max water temperature: 130°F
• Solenoid current: Typically 0.42 A inrush (higher draw)
• Filter: Optional external filter screen; no integral filter standard
• Internal bleed: Available via manual bleed screw
• Reclaimed water: Not specifically rated; designed for potable landscape irrigation
• Primary design intent: Residential and commercial landscape irrigation

Key differentiators:

• Material construction: Netafim’s glass-reinforced nylon resists corrosion from fertilizer-laden water in hydroponic systems better than the PVC/brass combination of the Hunter PGV-151. The stainless steel fasteners on the Netafim valve extend service life in wet greenhouse environments where fastener corrosion is a common failure point.
• Minimum pressure requirement: The Netafim Series 80 operates at a minimum of 7 psi versus Hunter’s 20 psi. Lower minimum pressure allows the Netafim valve to function reliably in gravity-fed or low-pressure irrigation systems where a Hunter valve would fail to open completely.
• Current draw: The Netafim’s 0.22 A inrush and 0.095 A holding current are significantly lower than Hunter’s 0.42 A inrush. Lower draw allows longer wire runs and more simultaneous stations on a single controller output, directly reducing infrastructure cost in large commercial installations.
• Integrated filter: The Netafim 1½ in model includes an EasyClean stainless steel filter as standard. Hunter requires a separate in-line filter, adding parts count and potential failure points.
• High-frequency cycling suitability: The Netafim Series 80 is explicitly designed for high-frequency irrigation cycling common in greenhouse substrate culture. The Hunter PGV-151 is rated for standard landscape irrigation schedules with fewer daily actuations.
• Reclaimed water certification: Netafim certifies the Series 80 for reclaimed water. Hunter does not specifically rate the PGV-151 for reclaimed water applications.

Compatibility & Operating Conditions

Compatibility information is drawn from the Netafim USA Series 80 product page and the canonical product data. Verify final installation against your local plumbing code and irrigation system design requirements.

Pipe and fitting compatibility: The 1½ in F × F threaded connections mate to standard 1½ inch female NPT or BSP pipe fittings depending on regional standard. Confirm thread standard with your local supplier before installation. The nylon body accepts standard pipe dope or PTFE tape on male pipe threads. Do not over-tighten—nylon threads can strip if torqued beyond hand-tight plus one additional turn.

Water quality compatibility: The Series 80 is suitable for potable water, fertilizer solution, and reclaimed water. The nylon body and Buna-N diaphragm are chemically resistant to common irrigation fertilizers, chelated micronutrients, and pH adjustment chemicals (citric acid, phosphoric acid, potassium hydroxide) at concentrations used in hydroponic nutrient programs. Avoid exposure to solvents or hydrocarbon-based pesticides in concentrated form—these can degrade Buna-N over time.

Pressure and flow compatibility: The Series 80 1½ in valve requires a minimum of 7 psi to open fully. Operating below 7 psi results in partial opening and unpredictable flow. Maximum operating pressure is 150 psi. The flow control stem can limit maximum flow below 110 GPM when intermediate settings are used. Pressure loss across the valve at full open is lower than across equivalent ball or gate valves due to the globe valve geometry and low-friction design.

Temperature compatibility: Maximum water temperature is 140°F. This rating covers standard greenhouse water temperatures, including nutrient solution temperatures in heated root zones. Water temperatures above 140°F will degrade the Buna-N diaphragm over time. Standard irrigation water at ambient greenhouse temperatures (65–85°F) is well within the operating range.

Controller compatibility: The 24 VAC solenoid is compatible with any 24 VAC irrigation controller capable of driving a resistive-inductive solenoid load. The low holding current (0.095 A) means the valve does not overload multi-station controllers. Compatible with standard irrigation controller platforms including Hunter, Rain Bird, Toro, Baseline, and similar 24 VAC output systems. For long wire runs, calculate voltage drop using the combined load of all simultaneously actuated valves to confirm adequate voltage delivery at the solenoid terminals.

Series 80 family size compatibility: If your system uses multiple Netafim Series 80 valves at different pipe sizes, the family covers 3/4 in (0.01–26 GPM), 1 in (0.01–44 GPM), 1½ in (0.25–110 GPM), and 2 in (0.25–176 GPM). Consistent valve technology across the size range simplifies maintenance—solenoid coils, diaphragm assemblies, and repair kits share design commonality within the family. An active aqua air pump can complement the irrigation setup by providing aeration to reservoir tanks or deep water culture systems within the same facility.

Usage Guidelines for the Series 80 Globe Valve

The usage guidelines below are based on Netafim’s published product specifications, standard irrigation system engineering practices, and the operational characteristics of the Series 80 design.

Orientation: The Series 80 globe valve is designed for horizontal mainline installation with the solenoid pointing upward (vertical solenoid position). Installing with the solenoid pointing downward can allow water and debris to accumulate in the solenoid housing and cause premature failure. Sideways orientations (solenoid at 90 degrees from vertical) are acceptable in most installations but verify with Netafim’s installation guidelines for your specific valve variant.

Flow direction: The Series 80 is a directional valve. The inlet and outlet are marked on the valve body. Install with flow direction matching the markings. Reverse installation (flow from outlet to inlet) will prevent the diaphragm from seating properly and may cause the valve to fail to close completely.

Setting the flow control stem: The integrated flow control stem is located at the top of the valve body, beneath the solenoid. Rotate the stem clockwise to reduce maximum flow, and counterclockwise to increase it. The stem can be adjusted while the solenoid is energized (valve open) to observe the effect on downstream flow rate or pressure. Set to the desired maximum flow for the zone, then verify downstream emitter pressure is within the design range. The flow control does not act as a pressure regulator—it limits volume but does not regulate pressure in the way a pressure-reducing valve does.

EasyClean filter maintenance: The integral EasyClean stainless steel filter on the 1½ in model should be inspected at the start of each irrigation season and cleaned or replaced if significant debris accumulation is visible. To service the filter, depressurize the mainline, unscrew the filter cap at the valve inlet, remove the filter screen, flush with clean water, and reinstall. No special tools are required for this maintenance operation.

Internal bleed operation: To manually open the valve without energizing the solenoid, use the manual bleed selector on the solenoid body. Turning the selector opens the pilot port and bleeds pressure from the diaphragm control chamber, allowing the valve to open. This function is useful for testing valve operation during system commissioning or troubleshooting, and for flushing mainlines without operating the irrigation controller. The Series 80 improved selector enables this operation without removing the solenoid from the valve body.

Solenoid replacement: If the solenoid coil fails while the valve body remains functional, the solenoid can be replaced without removing the valve from the mainline. Depressurize the line, unscrew the solenoid from the valve bonnet, install the replacement solenoid, and restore pressure. Replacement solenoids in 24 VAC, 24 VDC, 12 VDC, 12 VDC latching, and 120 VAC configurations are available from Netafim, allowing voltage conversion without valve body replacement.

Winterization: In freeze-prone locations, drain the valve at the end of the irrigation season. The nylon body can crack if water freezes inside the valve under pressure. Use the internal bleed selector to relieve pressure before draining. Install in valve boxes or insulated enclosures in climates with hard freezes.

How to Install the Netafim Series 80 Globe Valve

The installation steps below are based on standard solenoid globe valve installation practices and the design features of the Series 80. Always follow local plumbing and electrical codes and verify final installation with a licensed irrigation contractor for commercial greenhouse or field installations.

1. Plan the valve location before cutting into the mainline. Select a location that allows the solenoid to point upward (vertical orientation), provides enough clearance on both sides for pipe wrenches or thread seal application, and is accessible for future maintenance. Mark the cut point on the mainline. The 1½ in valve body adds approximately 5–6 inches of installed length to the pipeline. Account for this when laying out valve manifolds or valve boxes.
2. Shut off and depressurize the mainline. Close the upstream isolation valve and confirm system pressure has dropped to zero by opening a downstream drain or emitter. Never cut into a pressurized mainline. If the installation is in an existing irrigation system, note the pipe schedule and material before cutting to select appropriate threaded adapters if needed.
3. Prepare threaded pipe ends. Cut the mainline cleanly and install male-threaded pipe adapters on both the upstream and downstream pipe ends. Wrap male threads with two layers of PTFE thread seal tape, or apply pipe joint compound rated for use with plastic fittings. Do not use petroleum-based pipe dopes that can attack nylon thread surfaces.
4. Thread the valve onto the upstream pipe adapter. Confirm flow direction marking on the valve body before threading. Hand-tighten the valve onto the upstream (inlet) adapter first, then snug with a strap wrench. Do not use pipe wrenches directly on the valve body—use a strap wrench or wrap the valve body in protective material to avoid cracking. Typical assembly torque for 1½ in nylon threads is hand-tight plus one to one-and-a-half turns, not more.
5. Connect the downstream pipe adapter to the valve outlet. Thread the downstream (outlet) pipe adapter into the valve outlet port. Apply PTFE tape to the male threads before assembly. Snug to the same torque as the inlet connection. Verify the valve flow direction arrow aligns with actual flow direction in the pipeline.
6. Run the solenoid wiring to the irrigation controller. Use 18 AWG two-conductor direct burial irrigation wire from the valve to the controller panel. The Series 80’s low holding current (0.095 A) supports long wire runs without significant voltage drop. Protect all splices with waterproof wire nuts or direct-burial splice kits.
7. Connect solenoid leads to controller and ground. Connect one lead to the zone output terminal and the other to the common ground. Polarity does not matter for the 24 VAC model. Restore system pressure and inspect all threaded connections for leaks before proceeding.
8. Test valve operation from the controller. Activate the zone. The valve should open within one to two seconds and close cleanly on signal removal. If the valve does not open, verify 22–26 VAC at the solenoid terminals under load. If it does not close fully, confirm mainline pressure exceeds 7 psi.
9. Set the flow control stem and install valve box. With the zone pressurized and open, rotate the stem clockwise to reduce flow or counterclockwise to increase until zone flow matches the design rate. Place the valve in a standard irrigation valve box to protect the solenoid and wiring from UV and physical damage.
