VRT Unloader Valves

VRT unloader valves are essential pressure-regulating components used on professional and industrial pressure washers. They control and limit system pressure while protecting the pump during both operation and standby.

When the high-pressure spray gun is open, the VRT valve regulates pressure by diverting excess water through an internal bypass, maintaining a safe, preset working pressure. When the trigger gun is closed, the valve automatically redirects all flow to bypass at low pressure, allowing the pump to run unloaded and reducing heat, wear, and stress on internal components.

VRT unloader valves are ideal for hot and cold pressure washers where reliability, safety, and long pump life are critical.
