How It Works
When the spray gun trigger is released, the valve redirects water to bypass instead of forcing pressure back into the pump.
This prevents:
-
Pump damage
-
Overheating
-
Pressure shock
-
Motor overload
The result is safer operation and longer equipment life.
Applications
-
Professional pressure washers
-
Car wash equipment
-
Workshop cleaning
-
Industrial maintenance
-
Agricultural washing
Why Choose VB3
A properly sized unloader valve is essential for pump protection.
The VB3 offers precise pressure regulation and reliable operation for medium-flow, high-pressure cleaning machines.
