應用與選型指引
Size the orifice combination to the filling and draining profile of the line first - large bore for bulk air during fill, the small-orifice stage for residual release under pressure - then set the body rating (PN10, PN16 or Class 125/150) against the maximum line pressure, and confirm the stainless 304 float against the medium within the 0 to 80 C range.
常見問題
What does "compound" mean on an air release valve?
It means the single body combines both air functions: a large-orifice air-and-vacuum stage that admits or discharges air in bulk during filling and draining, and a small-orifice stage that vents air pockets that collect while the line runs under pressure. The benchmark page declares both stages in one DN50 to DN300 flanged unit.
Which pressure ratings does this execution cover?
PN10, PN16 and Class 125/150, flanged per DIN 2501 PN6/10/16 and DIN 3202. Match the flange drilling to the mating pipe standard rather than assuming interchangeability between the PN and Class tables.
What information is needed to quote a compound air release valve?
Nominal size within DN50 to DN300, the line pressure class, the medium (water, oil or gas per the benchmark page) and the working temperature against the 0 to 80 C limit. Those points fix the body material choice between ductile iron and carbon steel as well.

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。
