Unloader valve for maximum pressure 310 bar and maximum flow rate 80 l/m VB 85 PN: 60.0427.60

VB85 RV Unloader Valve – High Flow Pressure Regulator

The VB85 RV unloader valve is a professional high-capacity pressure regulating valve designed for industrial pressure washer systems operating at high flow rates.

When the spray gun closes, the valve redirects water to bypass, preventing pressure spikes and protecting internal pump components.
Its large flow capacity makes it ideal for heavy-duty machines where standard regulators cannot handle the water volume.

Main Features

• High flow capacity design

• Stable pressure regulation

• Protects pump seals and pistons

• Prevents pressure shock

• Heavy-duty brass construction

• Reliable continuous operation

• Suitable for hot water machines

• Designed for industrial applications

Technical Specifications

How It Works

When the trigger gun is released, the valve opens the bypass circuit and relieves pressure inside the pump.

This prevents:

• Pump damage

• Seal wear

• Overheating

• Hose vibration

The result is safer and more stable machine operation.

Applications

• Industrial pressure washers

• Heavy equipment washing

• Truck and fleet washing

• Agricultural cleaning systems

• Continuous duty cleaning plants

Why Choose VB85 RV

This valve is built for machines with high water volume.
It ensures reliable pressure control, reduces maintenance, and increases equipment lifespan in demanding working conditions.
