應用與選型指引
Choose this over the SS304 execution when the medium carries chlorides or other pitting triggers — the added molybdenum in SS316 is exactly for that duty. Both executions share the same DN15 to DN400, PN16 to PN40 envelope and DIN 3356 design basis, so the material decision, not the size range, is what separates them. End connection is flanged or butt weld; operation can be manual handwheel or actuated. For pressure above PN40 the bellow seal globe family is not the execution — move to a pressure-seal design.
常見問題
SS316 vs SS304 bellow seal globe valve — which should I specify?
Both share the same benchmark envelope: DN15 to DN400, PN16 to PN40, DIN 3356 design, DIN 3202 face-to-face. The difference is corrosion resistance: SS316 adds molybdenum, which resists chloride pitting, so chloride-bearing media (seawater-adjacent, brine, some process chemicals) select SS316 while general water, steam and mild chemical service is fine on SS304. The benchmark page shows both executions listing graphite packing, with the SS316 variant adding PTFE to the packing set.
Can this valve be actuated instead of handwheel operated?
Yes — the benchmark page lists handwheel operated, electric actuated and pneumatic actuated operation for this execution. For modulating duty a globe pattern gives controllable throttling; for on-off duty either actuation type works. Specify the actuation and supply medium (electric power or instrument air pressure) in the inquiry so the torque/force sizing comes back with the quotation.
What information is needed to quote an SS316 bellow seal globe valve?
Provide nominal diameter (DN15 to DN400), PN rating (PN16 to PN40), the medium with temperature and chloride content if known, end connection (flanged per DIN 2543 or butt weld), and operation preference. Quotation will confirm bellows material, packing set and the DIN 3230 test documentation.

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。
