應用與選型指引
Select this execution for venting air pockets on water, oil or gas mains from DN50 up to DN1200, where a single release orifice is enough and the screwed end connection suits the mounting boss. Confirm the PN10, PN16 or Class 125 rating against line pressure and the -20 to 180 C temperature window against the medium, and that a ductile iron body with an SS304 float matches the service chemistry.
常見問題
What does single release mean on this air valve?
It vents through one orifice controlled by a single float, releasing air that collects at pipeline high points as it accumulates. Combination valves add a second large-orifice kinetic stage for pipeline filling; the single-release execution suits lines where air arrives steadily during operation rather than in large slugs at fill.
Which materials does this execution use?
The benchmark page lists a ductile iron body and a stainless steel 304 float ball, rated PN10, PN16 or Class 125 across water, oil and gas service from -20 to 180 C.
What information is needed to quote a screwed single release air valve?
The main line size between DN50 and DN1200, the pressure rating (PN10, PN16 or Class 125) against operating pressure, medium and temperature within -20 to 180 C, and the screwed end connection detail for the mounting boss.

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。
