Check Valves

When a pump set system is used to deliver water under pressure to the nozzle distribution grid and particularly when two or more high pressure pump sets are manifolded together to deliver the correct water flow and pressure, non-return valves shall be installed to prevent pressurized water from returning to another pump. This is required to avoid pump damage and to avoid water by-passing to a non-used (idle) pump.

Various sizes of non-return valves are supplied, from ½” up to 2” sizes. The high pressure non-return valves can be mounted in any position either vertical or horizontal. It is important to install the non-return valves in the proper direction of water flow as marked on the non-return valves. The non-return valves are designed to withstand hydrostatic test pressures in excess of 5,800 psi (400 bar) to ensure maximum life cycle integrity and a trouble-free service life.

The non-return valves shall also be installed onto the FOGEX® Water Storage Systems (PSM’s) when two or more cylinder systems are manifolded together. This is to ensure that water does not return to an emptied system.
