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.


High-Flow Performance Advantages

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.

  • Skid-mounted systems
  • Custom wash equipment
  • Industrial pump systems
  • High-capacity cleaning applications

Performance Benefits

  • Reliable pressure regulation
  • High-flow capability
  • Reduced pressure spikes
  • Improved pump protection
  • Consistent cleaning performance
  • Reduced component wear
  • Long service life
  • Commercial-grade reliability

Signs an Unloader Valve Needs Replacement

Replace the unloader if you notice:

  • Pressure fluctuations
  • Excessive bypass flow
  • Water leakage around the valve
  • Reduced cleaning performance
  • Difficulty maintaining pressure settings
  • Pump cycling issues
  • Internal wear or corrosion
  • Inconsistent operation

Installation Notes

  1. Shut down the system and relieve all pressure.
  2. Verify compatibility with system flow and pressure requirements.
  3. Install using the appropriate plumbing connections.
  4. Apply thread sealant where required.
  5. Adjust operating pressure according to manufacturer specifications.
  6. Test for leaks and proper bypass operation.
  7. Verify stable pressure performance before returning the system to service.

Important: Ensure all pumps, hoses, guns, fittings, and accessories are properly rated for the intended operating pressure and flow capacity.


Maintenance Recommendations

  • Inspect regularly for leaks and wear.
  • Verify pressure settings during routine service.
  • Monitor bypass operation.
  • Maintain clean water filtration systems.
  • Replace worn seals and internal components when necessary.
  • Follow Mecline maintenance guidelines.
