應用與選型指引
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.
常見問題
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.

報價
可直接報價的詢問應說明：公稱口徑與壓力額定、閥體與閥座材質偏好、端部連接、操作方式，以及含溫度的使用介質。本頁的典型值為基準參考範圍；具有約束力的數值於報價時確認。

供應條件、訂購數量與交期按訂單議定——請在詢問時說明目的地國家與所需時程。
儲存與運輸
閥門儲存時應保護閥座與密封件免受紫外線、臭氧與變形影響，安裝前保留端面保護蓋；彈性體或 PTFE 閥座結構應避免長期戶外存放——閥座材料在陽光直射與冰凍條件下老化最快。
