All KITO® valves use a range of different valve sealings to suit the prevailing process conditions to assure low rates of leakage between valve seat and valve pallet.

Valve pallets for KITO® vacuum relief valves are designed either weight-loaded or spring-loaded, depending on the pressure settings required.

KITO® vacuum relief valves are used where closed systems are being emptied or cooled by their local environment, preventing, for example, negative pressure to damage storage tanks.

Series 765 Pressure Vacuum Breakers are designed to be installed to provide protection against back siphonage of toxic or non-toxic liquids. They feature a durable bronze body and a check valve and air opening port in one assembly. Maximum Working Pressure: 150psi (10.3 bar).

KITO® vacuum relief valves can also be equipped with a KITO® flame arrester that prevents flashback from atmosphere to storage tank. These KITO® vacuum relief valves can be used for atmospheric deflagration scenarios. There is not usually any risk of an endurance burning in typical applications involving a vacuum.

KITO® vacuum relief valves can be configured to suit prevailing national and international specifications and regulations. If you need assistance with this, please use our KITO® Sizing & Selection program (KISS) or contact our experienced KITO® sales team.
