應用與選型指引
Select this execution where inline maintenance matters: the three-piece split lets the center section carrying ball and seats be swung out without disturbing the end connections. Pick the body forging (CF8/CF8M stainless for corrosive media, WCB carbon steel for general service) and the trim (SS316 or SS304) against the medium, inside the -20 to 150 C window and the ASME B16.34 class range.
常見問題
What does the three piece construction add over two piece?
The center body section - ball, seats, stem packing - can be removed for service without breaking the end connections, because the body splits into two caps plus the center section. The benchmark parts list (body, cap, ball, seat, thrust washer, stem, stem packing, gland, spring washer, nut, handle cover) is all reachable through that split; a two piece valve still needs one end disconnected.
Which materials does this forged execution use?
The benchmark page lists CF8, CF8M and WCB for body and cap, SS316 or SS304 for ball and stem, PTFE for seat, thrust washer and stem packing, and SS304 for gland, spring washer and nut. That covers corrosive (CF8/CF8M + SS316) and general (WCB + SS304) duty in one forged platform.
What standards govern the execution?
ASME B16.34 for design, DIN 3202 for face-to-face, and API 598 for test and inspection, over a -20 to 150 C working temperature window per the benchmark page. Match the face-to-face against the mating piping before ordering a replacement into an existing spool.

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。
