Regulation valves

Unloader valves for high-pressure cleaners – with and without switch

For commercial cleaning companies, industrial plants and self-service car washes, our unloader valves are available in two versions and offer maximum efficiency, process reliability and cost savings. An unloader valve (also known as a circulation or relief valve) is a central component in high-pressure cleaning systems and plays a crucial role in safety, pressure regulation and equipment protection.

Unloader valves without switch

The classic version without a switch offers reliable pressure regulation and protects your system from overpressure.

Continuous pressure relief when the water flow is interrupted
Simple, robust design for minimal maintenance
Perfect for individual control via external circuits
Use in industrial and commercial applications

Unloader valves with switch

Our unloader valve with integrated pressure switch automatically regulates the water pressure and switches off the pump when it stops.

Automatic pressure relief when the gun is closed
Integrated shut-off function saves energy and reduces wear
Ideal for continuous operation in self-service car washes, fleet maintenance and building cleaning
