DIG 1″ In. Anti-Siphon Valve With 305DC Solenoid – 305DC-ASV-100

S305DC- ASV Anti-siphon Valves

The S305DC-ASV series plastic anti-siphon valves with 7-12 VDC solenoid can be used with our LEIT 2ET controller and two, four, and six station battery operated controllers. Designed for reliable operation, the anti-siphon valves feature flow control handles for flow adjustment and manual shutoff, internal manual opening via the solenoid and external bleed via the bleed screw for smooth opening and closing.
