應用與選型指引
Specify this execution where pump stop-transient noise or water hammer is the complaint - circulating-water, building-services and sewage pump outlets are the stated applications. Confirm body/seal material (both WCB on the benchmark page) and stem material against the medium temperature, stated as -20 to 120 C.
常見問題
What does the hydraulic buffer actually change?
It slows the disc over the last part of its closing travel, so reverse-flow arrest does not produce the sudden metal-to-metal stop that causes water hammer. The manufacturer positions the valve specifically for pressurised pump outlets in industrial circulating water, urban water supply, high-rise buildings and sewage duty.
What size and pressure range is covered?
2 in to 24 in (50-600 mm) and PN10/16/25 per the specification block, with standards EN593, DIN 2501 PN6/10/16 and DIN3202 K1.
What materials are offered on the benchmark page?
Body and seal in WCB (ASTM A216 cast steel) and stem in stainless steel 410, with water and neutral liquids as the stated medium between -20 and 120 C. Other executions should be confirmed with the supplier.

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。
