Bypass Valve Assembly
Part Number: BPV
Automatic bypass valve assembly enabling the supply of mains water should a pump set fail. The assembly features a special low headloss double check valve assembly (ED132), four full bore isolating valves and a drain tap.

The assembly shall feature a low headloss double check valve and four, full-bore spherical servicing valves. Proviso – the application must not be Fluid category 4 or 5.
