雙法蘭蝶閥
雙法蘭蝶閥以自身一體法蘭在兩個面均以螺栓接管，因此適用於對夾閥體無法信任承載的埋地、供水與泵站管線。產品範圍涵蓋 DN50 至 DN350，PN10 至 PN16，閥體與蝶盤為 WCB、球墨鑄鐵或 CF8/CF8M/CF3M，閥桿 SS420/SS431、NBR 密封與 RPTFE+石墨軸承，操作為蝸輪或執行器。設計依 BS EN 593 / BS 5155，面距依 EN558，法蘭依 ANSI B16.1 / AWWA C207 / EN 1092-2，測試依 API 598 / EN 12266-2。選型取決於此結構的低 PN 區間對管線等級、彈性密封對介質，以及法蘭鑽孔標準。

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。
