This professional grade anti-siphon valve replaces Rain Bird and other irrigation valves installed above ground with 3/4 in. female threaded inlet and outlet. It can be used with any 24 volt AC irrigation timer. Its unique reverse-flow design helps prevent flooding in the event of internal diaphragm failure, keeping the valve closed and saving water.

Anti-Siphon valves should always be installed at least 6 inches above the highest head on the valve line, and should never have another valve installed further down the line from the main valve. After installation and before startup, always the flush system of dirt and debris manually using the valve's external bleed screw.

Equipped with the additional advantage of adjustable flow control, this model helps prevent wasteful misting when water pressure is too high. A top mounted, easy turn flow control knob allows you to optimize flow to the zone, permitting sprinklers to water at their most efficient rate for more uniform coverage.

This valve can be applied with all types of watering devices including Rain Bird spray heads (1800, 600), and rotors (22SA, 32SA, 42SA+, 52SA, LG3 and AG5) as well as Drip zones when properly installed together with a pressure regulator and filter.

DAS-ASVF Series Valve Installation and Operation

Before Installation

Install master valves and pressure regulators as needed.
A pressure regulator is required if water pressure exceeds 150 PSI (recommended over 80 PSI).
Flush the system thoroughly until water runs clear.
Shut off the main water supply.

NOTE: For less than 3 GPM flow or drip applications, install a 200-mesh filter before the valve.

Connect Valve to Pipes

Apply PTFE thread-seal tape to the male threads on the adapters, screw into the valve and hand-tighten. (do not use PVC glue or pipe dope on adapter threads).
Apply primer and then PVC cement to the ends of the pipe and inside the adapters per manufacturer’s instructions.
Ensure the valve arrows face in the direction of water flow, and push valve onto inlet and outlet pipes until secure. Follow PVC cement instructions for cure time.

Connect Valve Wires

NOTE: Use watertight connectors and direct burial wire for all connections.

Connect one solenoid wire to a common wire (usually white). All valves can share the same common wire.
Connect the second solenoid wire to a power wire (usually colored).

Valve Operation

Manual Operation:

Manual on: Turn the solenoid counter-clockwise 1/4 turn. Do not unscrew completely. To close, hand tighten clockwise.
Flow control (select models only): Turn clockwise to restrict flow. Turn counter-clockwise to open flow.
Flush valve to clear debris: Turn the bleed screw counter-clockwise ONLY 1 turn. Flush one minute and turn clockwise to close.
