應用與選型指引
Select this execution where a lubricated plug valve would demand a grease schedule the line cannot carry - or where injected lubricant would contaminate the medium. Pick body and plug materials against the medium (LCB/WC6 for low and high temperature service, CF3M for corrosive duty), confirm the class rating, and match the end connection - flanged, socket weld, butt weld or screwed, each to its stated ASME/ANSI standard.
常見問題
How does a non-lubricated sleeved plug valve seal without grease?
The plug turns against a PTFE or PPL sleeve and seat set that provides the sealing surface, so sealing does not depend on injected lubricant - the benchmark page lists seat, seat ring, packing and gasket across PTFE, PPL, graphite and SS304+graphite with no lubrication line in the duty.
Which body materials and ratings does the execution cover?
The benchmark page lists body and bonnet in WCB, CF8, CF8M, CF3, CF3M, LCB and WC6, with plug in A105+ENP or SS304/304L/316/316L, sized DN15 to DN350 at Class 150 to Class 900 and PN16 to PN63.
What end connections are available?
The benchmark page declares flanged ends to ASME B16.5, socket weld ends to ASME B16.11, butt weld ends to ASME B16.25 and screwed ends to ANSI/ASME B1.20.1, with inspection and test to API 598 and API 6D.

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。
