Technical Specifications

What Does an Unloader Valve Do?

When the pressure washer trigger is released, the VRT3 unloader valve redirects the water flow away from the closed gun and into the bypass circuit. This protects the pump and other pressure washer components from excessive pressure.

Correct adjustment and installation are essential. Always confirm that the valve’s pressure, flow rate, temperature rating and connections are suitable for your pressure washer before ordering.
