How the VRT100-190D Works
The VRT100-190D automatically regulates system pressure by redirecting water flow when discharge flow is interrupted.
When the spray gun closes:
- System pressure rises
- The unloader piston activates
- Water is redirected through the bypass circuit
- Excess pressure is relieved
- Pumps and plumbing components are protected
When cleaning resumes:
- Water flow is restored to the outlet
- System pressure stabilizes
- Full cleaning performance returns immediately
This automatic operation helps maximize system reliability while reducing wear on critical components.

The dual bypass configuration offers several benefits:
- Improved bypass flow capacity
- Enhanced pressure regulation
- Reduced stress on pumps
- Better heat dissipation during bypass operation
- Greater flexibility for plumbing configurations
