三通旋塞閥
三通旋塞閥經單一塞體連通兩個入口與一個出口（或反之），分流或匯流的切換在閥門處完成，而非在由兩顆二通截斷閥組成的三通接頭中——適用於混合任務、輸送線選擇與取樣或沖洗取口。產品範圍涵蓋 DN15 至 DN300 結構，額定 Class 150 至 2500 與 PN10 至 PN420，依 API 599 與 API 6D 設計，閥體與閥蓋為 WCB、CF8、CF8M、CF3、CF3M、LCB 或 WC6，塞為 A105+ENP 或不鏽鋼等級，PTFE 或 PPL 閥座配石墨/PTFE 填料與 SS304+石墨墊片。面距依 ASME B16.10，法蘭端依 ASME B16.5 與 B16.47，對焊端依 ASME B16.25，檢驗與測試依 API 598。選型取決於通口布置（L 型或 T 型）、閥座材料對介質，以及迴路的壓力等級與端接型式。

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。
