IBR Valves
Supreme Valves supplies IBR approved valves for Indian boiler and steam circuits — primarily IBR gate, IBR globe and IBR check valves in ASTM A216 WCB. Use this hub to select the product page, then send a complete RFQ including design pressure, temperature and IBR form requirements.
What IBR approval means for valve buyers
Indian Boiler Regulations (IBR) govern design, manufacture and inspection of boilers and certain steam piping components. When a project calls for IBR certified valves, the purchase order must state IBR clearly so stamping, documentation and inspection routes are planned before manufacture.
Typical package: WCB gate (API 600 OS&Y) for isolation, WCB globe (BS 1873 style) for throttling, WCB swing check for non-return on feed and steam lines — plus moisture separators and traps on the steam main.

IBR gate, globe and check — typical boiler package
Indian boiler projects commonly release a single enquiry covering IBR gate valves for main steam and feed isolation, IBR globe valves for blowdown and regulated services, and IBR check valves on feed and steam non-return points. Moisture separators and traps complete the steam quality package. Supreme Valves quotes these as individual tags or as a consolidated WCB IBR package from Ahmedabad.
Always state design pressure, design temperature and whether third-party inspection is mandated. IBR paperwork timelines differ from plain commercial API 598 supply — early clarity avoids schedule risk.

FAQ
Which valves typically need IBR?
Gate, globe and check valves on boiler steam and certain feed lines under Indian Boiler Regulations. Confirm with the project boiler inspector — not every plant valve needs IBR.
Can Supreme Valves supply IBR stamped WCB valves?
Yes. State IBR on the RFQ with design P/T so the correct documentation and inspection path is followed.
What material is usual for IBR steam valves?
ASTM A216 WCB is the common cast carbon steel grade for saturated steam within its temperature limits. Higher-temperature alloys (e.g. WC6) are quoted when the steam condition requires them.
Where are the detailed product pages?
See WCB gate valve, WCB globe valve, WCB swing check valve and moisture separator pages linked above, plus the root IBR manufacturer page.
