Netafim 3/4″ 24 VAC Series 80 Two-Way Globe Valve w/ Flow Control & Encapsulated Solenoid 50 GPM Max Flow

The Netafim Series 80 3/4" Two-Way Globe Valve is a 24 VAC solenoid-operated control valve built for zone and master valve control in residential and commercial irrigation systems. Its nylon body and encapsulated solenoid deliver reliable on/off control with a manual flow adjustment that lets you fine-tune flow without additional inline fittings. Rated up to 50 GPM max flow and compatible with major two-wire control systems, this valve is a straightforward choice for growers and landscapers who need dependable automated water delivery.

Netafim Series 80 Globe Valve Specifications

Technical specifications are drawn from the canonical product record and dimensional attributes. The 3/4" inlet size and 24 VAC operating voltage are confirmed by both the product title and supplier description.

Why Choose the Netafim Series 80 Globe Valve

The Series 80 globe valve is designed around a few practical priorities: reliable automated switching, field-adjustable flow, and a construction that holds up in outdoor installations. Here is what the product record supports:

• Nylon body construction: The valve body is molded nylon, which resists corrosion and remains lightweight compared to brass or cast-iron alternatives. This makes it a practical fit for residential and light commercial irrigation lines where pipe loads and chemical exposure are routine concerns.
• Encapsulated solenoid: The solenoid coil is fully encapsulated, protecting its electrical components from moisture ingress. This is a meaningful distinction in outdoor installations where the valve may be exposed to rain, irrigation blowback, or high-humidity enclosures.
• Manual flow control built in: The flow control mechanism is part of the valve body rather than a separate downstream fitting. You can throttle flow at the valve itself, which simplifies installation and reduces the number of connection points in the line.
• Two-wire control system compatibility: The 24 VAC operating voltage is the industry-standard signal level used by the majority of residential and commercial irrigation controllers. The valve is compatible with major two-wire decoder systems, so it integrates into new and existing controller setups without requiring adapter hardware.
• Zone and master valve versatility: The two-way globe configuration supports both zone valve and master valve roles. A single valve model covers two common installation positions, which matters when stocking parts for a multi-zone system.

Best Uses for the Netafim Series 80 Globe Valve

This valve fits naturally into automated water management setups where a compact, solenoid-operated control point is needed at the 3/4" line size. Based on the product description and category placement in Hydroponic Systems & Water Management, the following applications are a direct match:

• Residential irrigation zone control: Use as a zone valve on a drip or sprinkler circuit fed by a standard 24 VAC irrigation timer. The 3/4" inlet accommodates typical residential main-line sizing.
• Commercial landscape irrigation: The valve is specified for commercial landscape use. The encapsulated solenoid and nylon body handle the duty cycles and environmental exposure common in commercial grounds maintenance.
• Master valve installation: Position on the main supply line upstream of zone valves to provide a fail-safe shutoff when no zone is active. This reduces line pressure on zone valves and limits water waste from a stuck-open zone.
• Greenhouse and indoor growing environments: Automated water delivery in controlled-environment agriculture benefits from the same reliable switching and flow control this valve provides in landscape applications. Pair with a compatible water management system to build out a more complete automated irrigation loop.
• Drip irrigation systems: Netafim is a principal manufacturer of drip irrigation components. This valve works naturally at the head of a drip zone, controlling flow to emitter lines or micro-tubing networks.

Compatibility & Operating Range

The Netafim Series 80 3/4" valve operates on a 24 VAC signal, which is the standard control voltage for residential and commercial irrigation controllers from all major manufacturers. This means it is electrically compatible with virtually any 24 VAC timer or decoder-based two-wire control system in common use.

At the 3/4" pipe connection, the valve fits standard NPT or slip fittings found in typical residential irrigation mainlines. The 50 GPM maximum flow rating provides substantial headroom above the flow demands of a standard residential zone, making it equally suitable for higher-demand commercial circuits.

The nylon body is compatible with municipal potable water and standard nutrient solution concentrations used in hydroponic irrigation. If your setup involves pH-adjusted water or mild fertilizer concentrations typical in drip fertigation, the nylon construction is appropriate. For highly aggressive chemical solutions, verify compatibility with the manufacturer’s chemical resistance data before installation.

For installations that also require water quality monitoring or filtration upstream, consider a 200-mesh inline filter to protect emitters and valve seats from particulate buildup.
