應用與選型指引
Select this execution where the pipework wants an angle body anyway - elbow positions, drain and flashing service where the right-angle path erosively attacks a straight globe - and pneumatic actuation drives the modulating duty. Pick the body casting against medium and temperature, choose metal sealing (IV grade) or soft sealing (VI grade) against the leakage requirement, and confirm the Cv range covers the loop.
常見問題
Where does an angle body earn its place on a control loop?
The right-angle flow path suits corner, drain and flashing duties where erosion would cut a straight globe seat, and it removes one elbow from the pipework. The benchmark page bodies the valve in WCB, WC6, CF8 or CF8M from DN20 to DN400 at PN16 to PN100 and Class 150 to 600.
What sealing and leakage classes are declared?
The benchmark page lists metal sealing at IV grade (0.01% of rated capacity) and soft sealing at VI grade (foam grade), with SS304/SS316/cobalt-chromium hardfacing alloy on seat and both plug sealing faces and SS304/SS316 cage and guide sleeve.
What is the controllable range and Cv coverage?
The benchmark page declares a 50:1 adjustable range (30:1 for Cv below 6.3) with percentage Cv 1.6 to 630 and linear Cv 1.8 to 690, and linear, percentage or quick-open flow characteristics.

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。
