How We Rebuild This Valve
Once a valve arrives, we tear it down fully, examine key surfaces, and replace worn or damaged parts using components we stock in-house, cutting out OEM lead times.
- Complete Disassembly: The unit is disassembled and all parts are laid out for individual inspection.
- Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
- 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.
