Pneumatic Pressure Adjusting Valves

Manufactured in the UK since 1970

The 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 or regulating valve. With compressed air switch off, the valve seat is fully open & by-passes pump flow at zero pressure.

As compressed air pressure is increased the valve seat & stem gradually close, diverting pump flow to the pressure discharge line. The valve can be operated remotely, switching
pump pressure on & off & adjusting pressure. This can be done with compressed air hoses up to 15m away from the valve or over any distance with electric cable.

Once the desired pressure us reached, the valve can be l locked where it will regulate pressure.

This allows single or multiple dry shut type jetting guns to be used whilst maintaining the set pressure.
