WCB Globe Valve
Supreme Valves manufactures the WCB globe valve in ASTM A216 Grade WCB to BS 1873 / API 623 style practice — OS&Y rising stem, bolted bonnet, Class 150–600 flanged RF. Globe construction gives predictable throttling for steam, condensate and process control isolation where a gate valve is not suitable.
Why specify a WCB globe valve
Globe valves use a disc that moves perpendicular to the seat, giving fine flow control and reliable shut-off on steam and process lines. BS 1873 and API 623 define cast steel globe valve practice for bolted-bonnet OS&Y designs. ASTM A216 WCB covers the majority of plant steam and hydrocarbon duties that do not require stainless or alloy bodies.
Search demand for WCB globe valve manufacturer India and Class 150 steam globe valve typically comes from boiler houses, process plants and EPC packages needing IBR-capable carbon steel globes alongside gate and check valves.

BS 1873 / API 623 WCB globe for steam and process
A WCB globe valve is the preferred hand valve when operators must throttle flow or shut off frequently under differential pressure. The disc travels onto a seat ring with a controllable characteristic; pressure drop is higher than a gate valve, which is acceptable on control and bypass services. BS 1873 and API 623 style bolted-bonnet OS&Y designs cover the cast steel size and class range used on Indian and export projects.
Plug discs are common for isolation. Parabolic or needle discs improve fine regulation on steam and condensate. Bellows-seal globes reduce fugitive emissions on hazardous or continuous steam service — declare bellows seal and expected cycle life on the enquiry.

IBR and boiler house packages
Boiler houses often buy globe valves together with gates, checks and moisture separators under a single IBR scope. Use the IBR valves page to structure the package RFQ, and link steam drying with a moisture separator upstream of PRVs.
Typical applications
- Steam and condensate throttling and isolation
- Boiler feed and blowdown circuits (IBR option)
- Process control isolation where modulation is needed
- Cooling water and utility regulation
- Bypass and recirculation lines around control valves
How to enquire (RFQ checklist)
- Size, quantity and pressure class
- End connection and face-to-face preference
- Disc type (plug / parabolic / needle) and trim material
- Service: steam / condensate / process; P and T
- IBR requirement
- Bellows seal or fugitive-emission packing if required
- Documents and inspection

FAQ
What standards cover WCB globe valves?
BS 1873 and API 623 are the common cast steel globe references. Face-to-face follows ASME B16.10. Testing follows API 598. Body material is ASTM A216 WCB.
When should I use a globe instead of a gate?
Use a globe when you need throttling, frequent open/close under differential pressure, or a positive soft shut-off characteristic. Use a gate for infrequent full-open isolation with lower pressure drop.
Are bellows-seal WCB globe valves available?
Yes. Bellows-seal designs are quoted for steam and toxic services where packing leakage must be minimised. State bellows seal and cycle life on the RFQ.
Can WCB globe valves be IBR approved?
Yes for boiler and steam lines under Indian Boiler Regulations. Confirm design pressure, temperature and IBR form requirements on enquiry.
