Pressure Equalising Valve PEV

This 1/2″ pressure equalising valve (PEV) is designed to supply both hot and cold water at equal pressures regardless of any pressure variation in the incoming supply, by automatically adjusting the higher hot or cold pressure to the level of the lower pressure. It can be used on multi-point/combi, fully modulating boilers, gravity systems, mains pressure hot water cylinders or any hot water system that provides constant temperature output.

The valve can be installed vertically or horizontally and at any distance before the mixer, provided it supplies only one mixer and there is no additional draw-off between the PEV and the mixer. The valve must be positioned where it is accessible should cleaning or maintenance be necessary. The water heating system must be able to deliver hot water at a constant temperature, regardless of demand from the system. The valve must be used in conjunction with shower valves that are designed to operate on equal pressure.

Connections: 4 x 1.2″ Male BSP
Min. pressure of hot/cold supply: 0.25 bar
Max. pressure of hot/cold supply: 10 bar
Max. water temperature: 80?C
