RFQ: WCB Butterfly Valve Class 150
WCB × Class 150 is the workhorse butterfly combination on international BOQs.
Why this page exists (29 similar lines in our RFQ archive)
International quotations repeatedly list WCB body + Class 150 RF + SS316 disc, often with gear or limit switch.
Across 952 recent quotation / BOQ lines synced into our RFQ system, this type–material–class pattern appears repeatedly. Pages like this match how EPC and trading houses write enquiries — not brochure marketing copy.

Frequently asked questions
Wafer or lug for Class 150 WCB?
Lug if dead-end or equipment removal is required; wafer for inline clamp-between-flanges.
Why SS316 disc on WCB body?
Common RFQ compromise — carbon steel body cost with stainless disc corrosion resistance.
Do you include limit switches?
Yes — specify LS / open-close feedback on the RFQ.
