Overview

The Hunter PGV-ASV Anti Siphon Valve is designed to pair water safety with dependable zone control in a single, field-proven unit. Built for 1-inch threaded connections and rated up to 150 PSI, it combines built-in anti-siphon protection with precise flow adjustment so you can manage lawn irrigation and drip setups without juggling multiple devices.

In everyday use, the valve sits at the heart of outdoor systems, ready to respond to weather and demand. Its rugged construction and thoughtful design mean you can rely on it across seasons—from dry spells to heavy rainfall—without sacrificing performance or ease of use.

Durable, weather-ready construction

The body is made from glass-filled nylon with stainless steel components, and a reinforced 6-bolt bonnet. This blend resists pressure, UV exposure, and wear, helping the valve perform reliably outdoors year after year.

Installation and compatibility made simple

Captive screws and standard 1" ports streamline mounting and connection, so installation stays straightforward for many residential and light commercial systems. The valve is compatible with both 24V AC solenoids and DC-latching battery controllers, enabling wired or battery-powered configurations without extra parts or rewiring.

Flow control that adapts to every zone

An integrated flow control knob lets you fine-tune water output for each zone, whether you’re hydrating a lush lawn, a vegetable bed, or a network of drip emitters. The ability to calibrate flow helps you balance coverage and minimize waste.
