應用與選型指引
Use this execution where a PN16 flanged line carries corrosive or hygienic-sensitive media and reverse flow must be blocked with low cracking pressure: the swing disc opens on forward flow and seats on reversal without actuation. For screwed small-bore CF8M points see the compact CF8M execution; for higher ratings move to the duplex or forged-steel swing check executions.
常見問題
Why CF8M for a swing check body?
ASTM A351 CF8M is the cast 316-grade stainless: it resists the corrosive media that would pit cast iron or carbon steel bodies while keeping the casting economy of a swing check, which matters at the DN100 flanged benchmark size.
What are the benchmark specifications?
Stainless steel swing check valve: ASTM A351 CF8M body, DN100 (4 inch), PN16, flanged end connection, sand-blasted surface treatment.
How is this execution connected and finished?
The collected benchmark page lists a flanged end connection on a PN16 rating at the DN100 (4 inch) size, with a sand-blasted surface treatment on the ASTM A351 CF8M cast body; body material, size, pressure rating, end connection and surface finish are the five fields the source records for this model.
訂購與文件
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。
