Features
- Disc is spring loaded for positive closure in any position.
- The disc is hardened, ground and lapped, to ensure leak free sealing over the valve’s full pressure temperature range.
- Seat is overlaid with Stellite or equal hardfacing.
- The integral seat hardfacing is overlaid directly onto the body base material, eliminating any possibility of leakage behind the seat.
- Flat, precision machined and lapped seating surfaces eliminate damage from high impact seating.
- All internal surfaces are accurately machined to provide maximum performance.
- Socket weld ends standard.
- Standard body and bonnet materials are carbon steel (ASME SA105).
- Code compliance with ASME 16.34 and the ASME boiler and pressure vessel code, Section I.
