当前位置－－>三偏心金属硬密封法兰蝶阀

     法兰连接金属密封蝶阀是本厂研制开发的三偏心结构型金属密封蝶阀，此产品具有安全可靠、流阻系数小，耐高温，适用于腐蚀性介质等特点。可作为调节和截止装置，广泛应用于蒸汽、热水、水、油品、煤气、天然气、化工、酸碱盐等工艺管路中。

    Flanged connection metal-seat butterfly valves are the three-dimension eccentric structure metal-seat butterfly valve which are developed by our factory. These products are safe and reliable, small coefficient of flow resistance, bear high temperature and suitable for corrosive medium and so on. They are widespread used for steam, hot water, water, oil goods, gas, metallic, acid alkali and salt technical pipeline as the adjusting and stopping setting.   

  

1、设计合理，结构紧凑，启闭迅速。            

2、开启力矩小，密封副无摩擦转动，阀门使用寿 命长。                                    

3、更换阀体材质和密封圈复合夹层可适用不同介质。

1. Reasonable design, compact structure, opening and closing fast.

2. Small open torque, seat almost without attrition and long serving life.

3. Different body materials and seal ring compound folder layer are suitable for different medium.
