應用與選型指引
Select this execution for dairy, food, beverage, pharmaceutical and cosmetic lines where the medium contacts the wetted parts and drainability or cleanability governs: the three-piece body lets the internals be swung out for inspection and the FDA-listed PTFE seat matches hygienic duty. Pick 1.4404/316L where chlorides or repeated CIP cycles demand the low-carbon grade; clamp ends for strip-down frequency, welded ends for permanent lines, threaded ends for instrument taps. Above 2.5 inch or outside the temperature window, move to the industrial floating or trunnion executions in this family.
常見問題
What is the difference between the 1.4401/304 and 1.4404/316L options?
Both are austenitic stainless listed for the body: 1.4401/304 is the general hygienic grade, while 1.4404/316L adds molybdenum and lowers carbon for better chloride and CIP-chemical resistance. The benchmark page lists both as body options, with 1.4404/316L also offered as the casting grade and an ASME BPE 1.4435 variant for forged bodies.
Which end connection should I choose?
The execution is offered clamped, welded or threaded. Clamped ends suit lines opened frequently for cleaning, welded ends suit permanent hygienic lines where joints must be smooth and crevice-free, and threaded ends suit small instrument and sampling taps.
What temperature and pressure does the PTFE seal allow?
The seal is PTFE to FDA 21CFR 177.2600, and the temperature window is -20 to 150 degree centigrade (up to the diaphragm gasket limit). Pressure depends on actuation and seal configuration as listed on the benchmark page.

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。
