複合式排氣閥
複合式排氣閥在單一組件中配對氣/真空功能與連續排氣功能：啟動時排放大量空氣、運行中釋放積聚氣囊、洩水時補入空氣以防真空與水擊——潔淨水輸送的標準高點閥，污水幹線則用重載版本。產品範圍涵蓋潔淨水單體組件 1"-8" 與雙體組件 10"-20"（VM-200C/201C/206C 系列，另有單體 SuperValve 變體），污水單體組件 1"-4"（801A/801AS/803A 系列，含全不鏽鋼結構），NSF 61/NSF 372 飲用水認證，符合 AWWA C512，浮球 T316 不鏽鋼，內件 316 不鏽鋼，彈性高低壓密封座。選型取決於潔淨水對污水任務、單體緊湊對雙體獨立維護，以及幹線要求的口徑區間。

訂購與文件
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。
常見問題
