夾管控制閥
夾管控制閥是常閉型夾管閥變體：壓縮空氣對抗彈簧回復開啟套管，洩放空氣則使閥門失效安全關閉——這是料倉安全系統與失效安全開關任務中、介質僅接觸套管的標準選擇。產品範圍涵蓋單缸閥 15 mm 至 50 mm 與雙缸閥 65 mm 至 250 mm，最大管線壓力按口徑段遞減（15-32 mm 為 5 bar、40-150 mm 為 3 bar、200-250 mm 為 2 bar），單缸開啟壓力 3-4 bar、雙缸 5.5-6 bar，鋁合金閥體配 PN10/16 法蘭連接，套管配方為天然橡膠（標準）、食品級 EPDM、EPDM 與氯丁橡膠。電磁閥、調壓閥、限位開關與電動氣動定位器可作附件。選型取決於口徑段的壓力限制、對抗彈簧回復開啟所需氣源，以及套管配方對介質。

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。
