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
