Pressure Regulating Valves

PRV and Gauge Board

The GD Energy Products Pressure Regulating Valve (PRV) is designed primarily for use on fixed speed pumps (e.g. electric motor pumps) as a means of controlling the system pressure. The PRV can be used either in a parallel system or in a “flow-through” system arrangement. It is essential that a pressure gauge is utilized for adjusting system pressure using the PRV. There are PRV models for the 10,000 - 15,000 PSI range, 20,000 PSI, and 40,000 PSI.

Pressure Regulating Valve

The PRV is a “needle-type” valve that allows excess flow to be released from the system and recirculated back to the pump. Water flow is controlled by turning the adjuster handle on top of the PRV. The hoses attach to the inlet/outlet in the valve body.

The 40,000 PSI valve is the best flow control valve on the market for 40,000 PSI. This valve is constructed with high-grade stainless steel, heat-treated for longevity. The repair kit allows for the valve to be repaired without removing the valve from the system.

Gauge Board

The GD Energy Products Gauge Board combines the Pressure Regulating Valve (PRV) with a standard pressure gauge for precision and added safety. The Gauge Board is a remote dump station which is highly recommended when the waterblasting work takes place at a distance from where the pump is located. Water flow is controlled by adjusting the Pressure Regulating Valve on the front of the device. The hoses attach to the water inlet/outlet in the base.


Overhaul of the Pressure Regulating Valve is easy and takes only a few minutes with the PRV Overhaul Kit, and may be done without removing the PRV from the system.
