This document provides an operation manual for ASVF anti-siphon valves and guidance on selecting the appropriate valve size. The valves are designed for use with standard sprinkler controllers with 24 volt AC output. The valve size is determined by the water flow of the main line or sprinkler circuit.
This manual provides instructions for the Rain Bird DAS-075 I ASVF 3/4" and DAS-100 I ASVF 1" anti-siphon valves. These diaphragm valves are designed for backflow prevention in outdoor watering systems, featuring flow control and atmospheric vacuum breaker capabilities. They are intended for use with standard sprinkler controllers that have a 24 volt AC output.

These valves are designed for use with static water pressures of a maximum of 150 PSI.
The valve size is determined by water flow: use 3/4" valves for 13 GPM or less, and 1" valves for 14 GPM or more.
No, for dirty water systems you must install a 100 mesh or finer wire filter or screen filter before the electric valves.
The valve must be installed at least 6 inches above the highest sprinkler or elevated piping in the circuit.
