Irritrol 311A-1 Intl. Bleed 1" Anti-Siphon Valve with FC

The Irritrol 311 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 & 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 & a captive Plunger solenoid. Plus, the actuator Module is removable as a single unit with the diaphragm & internal components held in place, which means no more lost diaphragm screws & springs during installation.
