球墨鑄鐵隔膜閥
球墨鑄鐵隔膜閥在相同的堰式密封概念背後提供更高強度的閥體:柔性隔膜與閥體堰脊接觸,由彈性體與襯裡——而非承壓殼——承載介質。產品範圍涵蓋球墨鑄鐵、鑄鐵或 WCB 閥體與閥盤,NBR 或 EPDM 襯裡與隔膜,DN15 至 DN250,PN6 至 PN16 或 Class 150,法蘭端接,操作為手動、電動或氣動,依 BS 5156、BS 6755、ASME B16.5、BS 4505 與 EN 1092。選型取決於隔膜彈性體對溫度與化學性質、管線壓力對 PN 區間、固含量,以及更換隔膜的維護通道。

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。
