305DC-ASV Anti-Siphon Valves

The 305DC-ASV series plastic anti-siphon valves with a 6-12 VDC solenoid can be used with our battery operated controllers and LEIT 2 ET solar powered controller. 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.

Anti-siphon Valve Features

  • Anti-siphon valve combines a remote control valve and backflow preventer in one unit
  • Constructed of UV-resistant PVC body and glass-reinforced nylon bonnet with a stainless steel spring and pins
  • High flow with low pressure loss
  • Normally closed
  • Operates in a wide range of flow rates
  • Utilizing self-cleaning EPDM diaphragm with seal design assembly
  • High performance, 6-12 VDC two-way magnetic solenoid
  • Flow control handle for water flow adjustment and manual shutoff
  • External or internal manual bleed allows quick and easy valve opening and closing
  • Excellent leak-free performance utilizing self-cleaning EPDM diaphragm and seal design assembly
  • Encapsulated EPDM seal washer built into the atmospheric backflow assembly
  • Encapsulated solenoid plunger for quick and easy service and maintenance
  • Manual or automatic operation
  • Smooth valve opening and closing prevents pressure surge hazards:
