Manual Pressure Adjusting Valves

Manufactured in the UK since 1970

This pressure adjusting valve is a versatile device to allow full control over pump pressure & flow. It has several functions & therefore is often referred to as a dump valve.

With no tensions on the springs, the valve seat is fully open & by-passes pump flow at zero pressure. As spring tension is increased the valve seat & stem gradually close, diverting pump flow to high pressure discharge line. 

Once desired pressure is reached, the valve can be locked where it will regulate pressure. This allows single or multiple dryshut type jetting guns to be used whilst maintaining the set pressure.
