Anti-Siphon Sprinkler Valve — 150 PSI, Integrated Flow Control","description":"\u003cstrong\u003eHunter PGV-ASV 1 in. Anti-Siphon Sprinkler Valve is a weather-tough irrigation valve with built-in anti-siphon backflow protection and integrated flow control for reliable zone management.\u003c\/strong\u003e\n\n\u003cp\u003eThis 1\" threaded Hunter valve combines backflow prevention and zone control into a single, serviceable unit engineered for residential and light commercial irrigation. Rated to 150 PSI and built from corrosion-resistant materials, the PGV-ASV is designed for outdoor cold-water service where dependable shutoff, easy installation, and seasonal durability are priorities. It works with both standard 24V AC solenoids and DC-latching battery controllers, letting you adapt the valve to wired or battery-powered systems without extra parts.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the anti-siphon feature protect my water supply?\u003c\/h3\u003e\n\u003cp\u003eThe PGV-ASV incorporates a built-in anti-siphon mechanism that prevents contaminated water from being drawn back into the potable supply, helping meet many local code requirements without adding a separate backflow device. Its design vents the valve internals above the highest downstream point to stop negative pressure events from creating backflow risks.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIntegrated anti-siphon design eliminates need for separate backflow assembly in many installations\u003c\/li\u003e\n  \u003cli\u003eAbove-ground venting reduces risk of siphon during pressure loss\u003c\/li\u003e\n  \u003cli\u003eMeets common backflow protection expectations for residential irrigation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and construction make this valve durable outdoors?\u003c\/h3\u003e\n\u003cp\u003eHunter built the PGV-ASV with a glass-filled nylon body, stainless steel hardware, and a reinforced diaphragm to resist UV, corrosion, and mechanical wear.
