應用與選型指引
Choose metal seating over resilient seating when medium temperature (up to 200 C here), abrasive solids or high cycling rules out EPDM/NBR seats; the page positions the execution for water, power, steel-smelting, chemical and papermaking pipelines. For higher temperature and tighter shutoff, the triple-offset executions are the next rung up.
常見問題
When does metal seating beat a resilient (soft) seat?
Above the elastomer temperature window - up to 200 C on this page - and in abrasive or high-cycle duty where soft seats erode; the eccentric design reduces seal friction so a metal-to-metal seal remains practical. The page states the T-type disc seal forms a linear sealing pair.
What sizes and pressures are covered?
DN100-DN1200 at PN10/PN16/PN24 to DIN3202 and DIN2501 PN10/PN16, with ductile-iron body and seal and a stainless steel stem.
How does this relate to double- and triple-offset valves?
The offset geometry - shaft behind the disc axis, offset from the pipe centreline, seat taper angled off the shaft - is what separates eccentric from concentric valves; adding the third taper offset gives the triple-offset execution. This page covers the general eccentric metal-seat execution; the dedicated double- and triple-offset pages carry those exact specifications.

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。
