應用與選型指引
Select this execution for PN10/16 water supply, drainage, steam or gas lines that need inline debris protection up to 200 C, where the body can be ductile iron and the filter element cast steel. Size it from DN15 to DN400 against the line, and pick the filter aperture between 0.8 mm and 3 mm against what the protected equipment tolerates - finer for control valves and meters, coarser for pump protection. Confirm DIN 2501/2532/2533 flange drilling matches the mating pipework.
常見問題
Why a ductile iron body for a Y strainer?
Ductile iron gives the Y body higher impact tolerance than grey cast iron at a lower cost than steel, which suits fixed PN10/16 water, steam and gas service. The benchmark execution pairs it with a cast steel filter element, so the wear part is harder than the body that carries it.
How is the filter aperture chosen?
The source execution covers apertures from 0.8 mm to 3 mm. Protecting control valves, meters and steam traps calls for the finer end of that range; pump suction protection tolerates the coarser end. The total mesh area is sized at roughly three to four times nominal diameter, so pressure drop stays modest while the aperture decides what is caught.
What information is needed to quote a ductile iron Y strainer?
Nominal size within DN15 to DN400, PN10 or PN16 class, the medium (water, steam or gas) and its temperature up to 200 C, the filter aperture between 0.8 mm and 3 mm, and the DIN 2501/2532/2533 flange drilling to match the pipeline.

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。

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。
