偏心旋塞閥
偏心旋塞閥將圓弧形塞擺入偏置閥座，僅在關閉位置以凸輪方式壓緊閥座面——每次行程閥座是被擦拭而非刮擦，因此在含砂、含纖維或結垢的水與污水服務中保持密封，而直動式旋塞會磨損閥座。產品範圍涵蓋鑄鐵 RF 法蘭結構，NBR 或 EPDM 閥座，尺寸 DN15 至 DN400（1/2 至 16 吋），額定 PN10 至 PN16 與 Class 150，操作為手動、氣動或電動。閥體與閥蓋有 A126 B、GG25、FC20、A536、A395、GGG40 或 GGG50 等級，塞用同等級材料，石墨或 PTFE 填料，結構組合含短、常規或文丘里通口型式、螺旋繞墊螺栓閥蓋、防靜電設計、防吹出閥桿與軟密封。服務為 -29 至 120 °C 的水、廢水與污水。選型取決於閥座彈性體對介質、RF 法蘭等級，以及閥井或廠區的驅動方式。

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。
