Rain Bird ASVF Anti-Siphon Irrigation Valve

An anti-siphon valve includes a built-in backflow preventer, which is a critical safety feature that stops contaminated irrigation water from being siphoned back into your home's potable water supply. Many local building codes require this specific type of valve for residential sprinkler systems.

Yes, this valve is designed to work with all standard 24 VAC residential sprinkler timers. It is a universal replacement or addition for most common irrigation setups.

The adjustable flow control handle allows you to fine-tune the water pressure and volume for each specific zone. This is particularly useful if you have different types of sprinklers or drip irrigation in the same system that require varying flow rates.

The internal and external manual bleed options allow you to turn the valve on or off manually without needing to access the controller. This makes it much easier to flush the system of debris or test the zone during installation and routine maintenance.

Yes, it is built to handle a maximum operating pressure of 150 psi. Its glass-filled nylon construction is specifically engineered to withstand the stress of harsh water conditions and high-pressure environments.

It uses standard 3/4-inch NPT female connections, so it installs like most other inline valves. However, because it is an anti-siphon valve, it must be installed at least 6 inches above the highest sprinkler head in the zone it controls to function correctly.
