What an Unloader Valve Does
The VRT100-190 is designed to:
- Regulate pressure within the system
- Divert water flow during bypass operation
- Protect pumps from damaging pressure spikes
- Improve system reliability
- Extend equipment service life
- Maintain consistent cleaning performance
When the spray gun is closed, water is redirected through the bypass circuit until spraying resumes.

The VRT100-190 is ideal for systems requiring:
- High-volume water flow
- Consistent pressure control
- Multi-gun operation
- Reduced system wear
- Reliable bypass performance
- Commercial-duty durability
Its 26 GPM capacity makes it suitable for larger cleaning systems that exceed the capabilities of standard unloader valves.
