WCB Water Pressure Reducing Valves
WCB water pressure reducing valves are the cast carbon steel (WCB) execution for water and waste water mains: the benchmark execution covers DN50 to DN600 at PN10/16, flanged per DIN 2501 PN6/10/16 and BS 5155, with WCB body, stainless steel seal and stem, working from 0 to 120 C.

Application & selection guidance
Size by the flow-stabilization duty and the inlet-to-outlet pressure differential first - the DN50 to DN600 span covers distribution mains and building services - then set PN10 or PN16 to the upstream rating, and confirm the 0 to 120 C window covers the water temperature. The stainless seal and stem suit continuously wetted duty.
Frequently asked questions
Why a WCB body for a water pressure reducing valve?
WCB cast carbon steel gives a higher strength envelope than cast iron at the same wall, which matters on the larger ends of the DN50 to DN600 range and where surge or elevated line pressure is expected. The benchmark page pairs it with a stainless seal and stem for wetted durability.
Which sizes and ratings does this execution cover?
DN50 to DN600 at PN10/16, flanged per DIN 2501 PN6/10/16 and BS 5155, for water and waste water from 0 to 120 C. The wetted seal and stem are stainless steel and the body is WCB, so a nominal size, the PN10 versus PN16 rating choice and the flange drilling fully specify the execution within the collected range.
What information is needed to quote one?
Nominal size, upstream and downstream pressure, flow rate and the water temperature. With the benchmark execution those points fix the PN10 versus PN16 rating and the flange drilling in one pass.
Ordering & documentation
Documents
Ask for the documentation set you need with the inquiry β typical items for this execution (material certificates, test reports to the listed inspection standard, dimensional drawings) are confirmed and supplied with the quotation.
Quotation
A quotation-ready inquiry states: nominal size and pressure rating, body and seat material preference, end connection, operation, and the service medium with temperature. Typical values on this page are benchmark reference ranges; the binding values are confirmed at quotation.
Sample & supply
Supply terms, order quantities and lead time are agreed per order β state the destination country and required schedule with the inquiry.
Storage & shipping
Store valves with seats and seals protected from UV, ozone and deformation, keep end-face protectors on until installation, and for elastomer- or PTFE-seated executions avoid prolonged outdoor storage β seat compounds age fastest in direct sunlight and freezing conditions.
