應用與選型指引
Apply this execution wherever a supply line must shut or modulate with tank level - filling make-up basins, cooling tower basins or reservoir inlets - without an electric control loop. Set DN50 to DN600 to the fill-flow demand, PN10 or PN16 to the supply pressure, and keep the duty within water or waste water up to 80 C.
常見問題
How does a float control valve hold the level?
A float pilot on the water surface senses level and hydraulically positions the main valve: open while the level is below setpoint, then closed as the level reaches it. No external power is needed. The benchmark execution covers DN50 to DN600 flanged bodies for this duty.
Cast iron or ductile iron body?
The benchmark page lists both: cast iron covers standard water duty, ductile iron where impact or surge toughness matters. Both share the stainless seal and stem and the 0 to 80 C window.
What information is needed to quote one?
Nominal size within DN50 to DN600, supply pressure class (PN10/16), the set-level behavior required and the water temperature. The flange standard follows from the pipe class.

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。
