角式控制閥
角式控制閥在單一閥體內將流動路徑轉向 90 度，將截止型控制閥的調節內件與角閥幾何合而為一——涉及排放口、高壓差或以閥代彎頭時的標準選擇。產品範圍涵蓋 DN20 至 DN400，PN 16 至 PN 100 / Class 150 至 Class 600，端接為法蘭、RF、MF 與 RTJ，閥體 WCB/WC6/CF8/CF8M，密封面 SS304/SS316/鈷鉻硬面合金，流量特性為線性、等百分比與快開，Cv 依特性自 1.6 至 690，金屬密封洩漏等級 IV 與軟密封等級 VI，面距長度在該口徑範圍為 115 mm 至 475 mm。選型取決於閥門承擔的壓差、閥座材料對介質，以及金屬或軟密封所要求的洩漏等級。

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。
