Unloader valve for maximum pressure 390 bar and maximum flow rate 40 l/m VHP39 PN: 4072000011

VHP39 Unloader Valve – High Pressure Washer Regulator

The VHP39 unloader valve is a heavy-duty pressure regulating valve engineered for high-pressure cleaning machines operating at extreme working pressures.

The valve automatically redirects water to bypass when the spray gun closes.
This prevents pressure spikes, reduces mechanical stress, and increases pump lifespan.

Its robust brass body and industrial design make it suitable for continuous professional operation.

Main Features

• Designed for high pressure systems

• Stable and precise pressure regulation

• Protects pump seals and pistons

• Reduces vibration and pressure shock

• Heavy-duty brass construction

• Reliable continuous operation

• Suitable for hot water applications

Technical Specifications

How It Works

When the trigger gun closes, the valve opens the bypass circuit and releases pressure inside the pump.

This prevents:

• Overheating

• Seal wear

• Pump damage

• Hose vibration

The machine runs smoother and lasts longer.

Applications

• Industrial pressure washers

• Construction cleaning

• Heavy machinery washing

• Professional cleaning contractors

• Hot water cleaning equipment
