應用與選型指引

Select this execution for utility and process lines - water, oil, gas and mildly corrosive liquids - where a threaded or butt-weld two-piece valve covers the duty at PN1.6 to 6.4 MPa and DN15 to DN100. Pick the body family (CF8/CF8M stainless for corrosive media, cast iron or carbon steel for utility service) against the medium, and confirm the ANSIB16.25 butt-weld standard where welded ends are specified.

常見問題

What media is this threaded ball valve execution rated for?

The benchmark page declares water, oil, gas and some corrosive liquid. For the corrosive end of that range the CF8/CF8M stainless body with SS304 ball, SS304 stem and PTFE seal ring, gasket, thrust washer and packing is the matching material route; cast iron and carbon steel bodies serve the utility end.

Which sizes and pressures does the execution cover?

The benchmark page lists DN15 to DN100 nominal diameter at PN1.6 to 6.4 MPa nominal pressure, with butt-weld ends to ANSIB16.25. That envelope covers typical utility and process branch lines; check the dimension table for the per-size face-to-face and bore.

How does the two piece construction affect maintenance?

The two-body split lets the ball, seats and seals be reached from one end without removing the valve body from the line - the benchmark parts list (body, bonnet, ball, stem, gland nut, washer, stem nut, seal ring, gasket, thrust washer, packing, handle) is fully serviceable through that split. Plan maintenance access on the side that carries the removable body half.

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。
