Rain Bird 100ASVF - 1" Anti-Siphon Irrigation Valve with Flow Control

Rain Bird manufactures only the highest quality valves. Use ASVF series valves in locations where the use of a separate pressure vacuum breaker (PVB) or a double-check valve is required by city codes to protect against back flow. Check your local city codes to determine what type of valves are required.

Anti-Siphon valves are installed above ground and will prevent back flow if properly installed. Anti-Siphon valves should always be installed at least 6" above the highest head on the valve line, and should never have another valve installed further down the line from the main valve. Our Anti-Siphon valves also feature our patented vacuum breaker–available for automatic or manual applications. All of our Anti-Siphon valves work with any standard sprinkler timer.
