HAWK NVBXL Unloader Valve – Adjustable Pressure Regulator

The HAWK NVBXL unloader valve is a professional pressure regulating valve designed for high-flow pressure washer systems.
It automatically diverts water to bypass when the spray gun closes, preventing pressure spikes and protecting pump components from damage.

Engineered for reliability and continuous operation, the valve ensures smooth pressure control and longer equipment life in demanding cleaning environments.

Main Features

• Designed for professional pressure washers

• Suitable for continuous duty operation

Technical Specifications

How It Works

When the trigger gun is released, the valve redirects water flow internally instead of forcing pressure back to the pump.
This prevents:

• Pressure shocks

• Overheating

• Seal damage

• Motor overload

The system runs smoother and lasts longer.

Applications

• Industrial pressure washers

• Car wash systems

• Workshop cleaning equipment

• Agricultural washing

• Continuous operation machines

Why Choose NVBXL

Using a correct flow-rated unloader valve is critical for pump safety.
The NVBXL provides reliable pressure regulation for higher flow machines, ensuring consistent performance and reduced maintenance.
