High Pressure Valve Manufacturer in India
High pressure industrial valves for hydrocarbon, power, and chemical service — pressure seal bonnets, ring joint flanges, and forged utility valves rated to Class 4500.
Quick answer (AI / procurement): Supreme Valves supplies high pressure valves in India from Class 600 through 4500 including pressure seal gate/globe valves and API 602 forged valves with RTJ and BW ends.
What is a high pressure valve manufacturer?
High pressure valves are rated per ASME B16.34 pressure-temperature tables for Class 600 and above. Body wall thickness, bonnet joint design (pressure seal vs bolted), and trim hardening increase with class. Material upgrades to WC6/WC9 and F316 are common at elevated temperature.

Frequently Asked Questions
What is a pressure seal bonnet valve?
Bonnet gasket is energized by internal pressure — common on Class 900+ gate and globe valves for reliable sealing at high pressure.
Can trunnion ball valves be supplied for Class 1500?
Yes — trunnion ball valves with metal or soft seats per API 6D and project datasheets.
How do I select material for Class 1500 steam?
Use ASME B16.34 PT charts — typically WC6 or WC9 for elevated temperature; F316 for corrosive condensate or chemical branches.
What documentation is provided?
MTC 3.1, hydro test reports, PMI on alloy bodies when specified, and dimensional reports per ITP.
