The Anti-Siphon Valve is used on above ground storage tanks to prevent spillage and to avoid other potential hazards.

Anti Syphon Valve

In the event a siphon occurs due to a rupture in the product pipe line, the valve will automatically stop the product flow. The valve is a normally closed check valve and will resist hydrostatic head pressure and prevent siphoning. The anti-siphon valve features a rust resistant epoxy coated cast iron body, precision machined bronzed seat, Bunga-N seals and is also available with pressure relief valve to relieve thermal expansion.
