Check Valve – High Performance Cask Ale Demand Valve

Check Valve (Demand Valve) 3/8" John Guest IN + 1/2" Barb Tail OUT.
This unit is used in the beer line just before the beer engine to stop the beer flowing forward through the beer engine when there is no demand (pump not being pulled).

This unit has a working pressure of between 0 - 45 PSI with no judder (rattle).

This means, if required, and using gas assisted pumps, the gas pumps can be run at beer cellar ring-main pressure (38PSI) without any performance variation across your beer engine range. This will create a great advantage when using 1/2pt pull beer engines which require a higher feed pressure.

Another advantage is this unit can be refurbished in the future at a fraction of buying new due to being screwed together not riveted.

 If you are going to use this valve to stop siphoning in a none pressurised system in PVC hose you will most probably require the adaptor fitting for the inlet to make this into a barbed tail. This is product PI251216S
