Disassembly and Rebuild Procedure

Each valve goes through teardown to expose wear and buildup. After mineral bath cleaning, we replace damaged parts and reassemble the unit to spec.

  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.
  • Complete Disassembly: The unit is disassembled and all parts are laid out for individual inspection.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.

Testing and Bench Verification

With over a dozen dedicated flow test stands and a Hagenbush proportional valve system, we verify flow curves, hysteresis, frequency response, and more. Performance reports and graphs are available for purchase on request. Our functional testing verifies consistent performance.
