應用與選型指引
Use this execution as the reference point for Class 800 small-bore stainless isolation: the forged A182 F316L body and socket-weld end suit high-pressure instrument and process headers where a cast Class 150-300 body would be the weak point. Floating-ball seating is the right design at this size; trunnion mounting takes over at larger diameters and higher classes.
常見問題
Why forged A182 F316L instead of a CF8M cast body?
The page specifies ASTM A182 Gr.F316L - a forged wrought material with a denser grain structure for high-pressure, high-integrity service; at Class 800 the forged body is the standard route where a cast floating body would not carry the rating.
What are the exact specifications of the benchmark model?
Model LD 17 BV 18: full bore floating ball valve, ASTM A182 Gr.F316L, RPTFE seal and seat, Class 800, 1 inch, socket-weld connection.
Does the floating design still work at Class 800?
At 1 inch bore the line pressure seats the floating ball downstream onto the RPTFE seat without excessive operating torque; trunnion-mounted executions take over as size grows, as the 24-inch SS316L trunnion benchmark page in this family shows.

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。
