Rain Bird Air Controls & Parts

Overview

The RAINBIRD NATIONAL SLS DASASVF100 is a 1-inch Sure Flow Automatic Anti-Siphon Valve designed for professional-grade irrigation system control. This valve features a reverse flow design that helps prevent flooding in the event of an internal diaphragm failure by keeping the valve closed, conserving water. An adjustable, top-mounted flow control knob allows technicians to reduce misting caused by excessive water pressure and optimize flow to each zone for more uniform sprinkler coverage. It ships in a package quantity of 5 units, making it well suited for multi-zone installation jobs. This anti-siphon valve is intended for residential and light commercial irrigation systems where backflow prevention is required at the zone level. The built-in anti-siphon design eliminates the need for a separate backflow preventer at each zone valve location. It is commonly installed in lawn and landscape irrigation applications by licensed irrigation contractors or qualified plumbing professionals. The external bleed screw allows manual flushing of dirt and debris from the system immediately after installation and before initial startup, which is a required step before placing the valve in service.
