Repair Process
The process begins with disassembly and visual evaluation. We then clean, replace worn pieces, and reassemble the valve to restore its function.
- Complete Disassembly: The unit is disassembled and all parts are laid out for individual inspection.
- 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
With our 13-stand test facility 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 pre-shipment testing verifies spec-level operation.
