應用與選型指引
Select this execution where a WCB carbon steel body suits the line - steam, thermal oil and general industrial service - and a bellow seal is wanted to cut fugitive emissions at the stem. Confirm the PN16 to PN40 rating covers the operating pressure, pick flanged versus buttweld ends against the pipework, and match the per-size DIN 3202 face-to-face and bolting table to the mating flanges.
常見問題
What materials make up the carbon steel bellow seal globe valve?
The benchmark page lists body and bonnet in carbon steel, disc and seat ring in A105+13Cr, stem in F6a, gasket in SS304+graphite, graphite packing, an SS420 gland with WCB gland flange, and carbon steel eyebolts and nuts - a matched carbon-steel boundary and trim set.
Which standards govern this execution?
The benchmark page declares DIN 3356 for design and manufacture, DIN 3202 for face-to-face dimension, DIN 2543 for flange end dimension, and DIN 3230 for inspection and test, over DN15 to DN400 at PN16 to PN40.
What is needed to quote this valve?
Nominal size within DN15 to DN400, the PN16 to PN40 class against line rating, end connection (flanged or buttweld), and the actuation choice - handwheel, electric or pneumatic - from the operation line of the benchmark page.

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。
