Irritrol 311A Series Anti-Siphon Valves

The Irritrol 311A Series offers a comprehensive package of performance-enhancing features
Beginning with the reliability of a leak-proof, double-beaded, nylon-reinforced Buna-N diaphragm, the strength of glass-filled nylon and the expanded range of a maximum working pressure rating of 150 psi, the 311 Series’ list of features easily outdistances the competition. Compatibility with the OmniReg® modular pressure regulator make them the industry’s only anti-siphon valves with a pressure regulation option. Additional features include an upgraded bonnet design, a self-cleaning metering system for dirty water applications and a captive plunger solenoid. Plus, the actuator module is removable as a single unit with the diaphragm and internal components held in place, which means no more lost diaphragm screws and springs during installation.
