Repair Process

Our team disassembles each valve to assess internal wear. After ultrasonic cleaning, we install replacements and reassemble and verify operation.

  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.

Testing and Bench Verification

Each MASTER PNEUMATIC PR180M-6 is tested on a dedicated flow bench before it ships. We check pressure, flow, leakage, and response characteristics against published specifications. Our pre-shipment testing verifies consistent performance.

Repair, Rebuild and Exchange Options

Beyond standard maintenance, we offer specialized reconditioning for your MASTER PNEUMATIC PR180M-6 unit. Our teardown process includes pressure testing and spool evaluation, using only replacement replacement components.

Maintenance Tips
