Component-focused process review
Valve bodies are pressure-boundary components whose cast geometry, seat and stem locations, flange or thread connections and final leakage requirements must work together. We plan the machining datums from the sealing system backward rather than treating the casting and machining as separate purchases.
Common purchasing priorities
- Pressure class, test pressure and allowable leakage
- Media, temperature and corrosion exposure
- Seat, stem and bore concentricity or positional relationships
- Wall transitions and machining depth near pressure boundaries
- NDT, material verification and traceability requirements
- Surface treatment or passivation after machining when specified
Integrated supply
Casting, precision machining, NDT and hydrostatic or pneumatic verification can be coordinated as one controlled route for pressure-retaining valve bodies.
Start with the application
Provide the pressure and temperature range, media, connection type, seat/stem datum scheme and the required NDT and pressure/leak-test acceptance criteria.
