我公司研制的軟密封中線對夾式蝶閥，雙偏心法蘭式蝶閥結構緊湊，90°回轉開關輕松，

密封可靠，使用壽命長，被廣泛用于水廠、電廠、鋼廠、造紙、化工、飲食等系統供排水中，作為調節和截止使用。

二、手柄對夾式蝶閥特點

 

1、本閥采用雙偏心結構，具有越關越緊的密封功能，密封性能可靠。

2、密封副材料選用不銹鋼和丁腈耐油橡膠配對，使用壽命長。

3、橡膠密封圈即可位于閥體上，也可以位于蝶板上，可適用不同特點的介質，供用戶選擇。

4、蝶板采用框架結構，強度高，過流面積大，流阻小。

5、整體烤漆、能有效地防止銹蝕且只要更換密封閥座密封材料，就可使用于不同介質。

6、本閥具有雙向密封功能，安裝時不受介質流向的控制，也不受空間位置的影響，可在任何方向安裝。

7、本閥結構獨特，操作靈活，省力，方便。
