  • 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 is bench-tested against published performance specifications.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.

Hydraulic Testing Process

We carry out full diagnostics on every valve, including flow gain, leakage, pressure shift, and frequency testing. Our test facility supports performance logging and report generation. Our pre-shipment testing verifies consistent performance.
