凸耳式蝶閥
凸耳式蝶閥在閥體周圍設有螺紋凸耳，蝶盤可隔斷管線一側而另一側仍被法蘭封住——這是蝶閥家族中服務於端頭（dead-end）與便於分段拆除的版本。產品範圍涵蓋不鏽鋼系列 DN40 至 DN300，PN10 至 PN40 / Class 150，閥體為 SS316L、碳鋼、鑄鐵或球墨鑄鐵、PTFE 軸套、EPDM/NBR/PTFE 閥座、閥桿自 SS410 至鎳銅合金、蝶盤自鋁青銅至 SS316，操作為手柄、蝸輪或執行器。設計依 API 609，面距依 API 609 / MSS SP-67 / SP-68，測試依 API 598。選型取決於凸耳結構對端頭壓力、閥座材料對介質，以及管徑下的驅動選項。

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。
