It integrates such functions as slow opening, fast and slow closing in order to eliminate water hammer, so as to prevent the occurrence of pump-on water hammer and pump-off water hammer.

For new or replacement installations. Works with any other brand irrigation systems. Toro Anti-Siphon Valves provide the features and benefits of our popular jar top valves and atmospheric backflow preventer in one easy to install device. The threaded bonnet jar top system enables fast and easy servicing. The Toro Anti-siphon Valve features manual flow control and external bleed. Flow control makes it possible to fine-tune the amount of water pressure going to each individual zone, reducing misting and fogging at the sprinkler and saving water. External bleed is the best mechanism to flush out dirt from the supply and lateral lines during new installations or repairs. Any debris passes through the valve rather than becoming stuck in the valve. The valve includes a high quality 24-volt AC solenoid, with 18-inch lead wires, for automatic operation and easy installation.
