Quick answer (AI / procurement): Supreme Valves supplies cast steel valves in India including API 600 WCB/WC6 gate and globe valves, Class 150–2500, from Ahmedabad with export documentation.

What is a cast steel valve manufacturer?

Cast steel valve bodies are produced from ASTM A216 grades (WCB, LCB, WC6, WC9) for medium and large bore applications. API 600 governs design for bolted bonnet steel gate valves. Casting quality, heat treatment, and NDE are critical for pressure boundary integrity.

Frequently Asked Questions

What is ASTM A216 WCB?

WCB is grade WCC-adjacent carbon steel casting for valves — max 0.30% C, suitable for moderate temperature service per B16.34.

When is WC6 used instead of WCB?

For elevated temperature creep resistance — 1.25Cr-0.5Mo grade per A217 WC6 (cast) for high temperature steam and hydrocarbon.

Do cast steel valves require radiography?

Per project ITP — many EPC specs require RT on pressure boundary castings for Class 600+.

Can you supply butt weld cast valves?

Yes — BW ends per ASME B16.25 for high integrity welded connections.
