應用與選型指引
Use this execution for very large water, wastewater and sludge lines where a single-mass swing disc would slam: the maintenance-free, replaceable-disc construction and optional rubber lining are the stated differentiators for high-wear and corrosive duties. Confirm flange drilling to DIN 2501 and the medium temperature window -20 to 120 C.
常見問題
Why two discs instead of one?
Two discs on one hinge pin each carry half the mass and travel a shorter arc to the 45-degree seat, so closing energy - and therefore slam and water hammer - is lower than an equivalent single-disc swing check. The manufacturer also states the disc is the only moving part and can be replaced without removing the valve from the pipeline.
What sizes does this execution reach?
The specification block lists DN1000-DN15000 at PN10/16 to DIN 2501 PN6/10/16 - an extreme large-diameter water range; bodies are cast iron or ductile iron with brass/NBR sealing options.
Is it suitable for slurry and vertical flow?
The page states the unrestricted full-flow design suits slurries and sludges including vertical upward flow, with optional rubber lining for high-wear or corrosive applications; independent process, cycle and performance test report certification is stated as available on request.

文件
請在詢問時一併說明您需要的文件組合——此結構的常見項目（材質證明、按所列檢驗標準的測試報告、尺寸圖）將於報價時確認並隨附供應。
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。
樣品與供應
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。
