Notes
- All valves are manufactured by Supreme Valves India as per our standard specifications.
- End connection type and pressure rating must be specified by the purchaser.
- For high-temperature service (> 200 deg C), PEEK or SS316 + graphite seat material is required.
- For cryogenic service (below -50 deg C), extended bonnet and cryogenic packing are required.
- For marine / seawater service, Nickel-Aluminium-Bronze (NAB / C95800) body and trim is recommended.
- All valves are factory-tested per API 598: hydrostatic shell test 1.5 x design pressure, seat leakage test 1.1 x design pressure (zero visible leakage), functional test (torque, full stroke, locking device).
