Size:DN50-DN2200
Function:
Isolating valve(on/off),regulating valve.Double flanged butterfly valve can be used at end of pipe line,maximum pressure not larger than 50% of the rated pressure.
1.The double flanged butterfly valve is mainly assembled by valve body,valve disc,shaft,seat and actuator.90 degree open & close rapidly and the torque is small, easy to operate.The valve seat is vulcanized on the valve body and can make the valve body completely separated from the medium,can be used in bad enviroments and have long service life.When the valve is closed,bi-directional zero leakage.
2.Compact construction results in low weight,less space in storage and installation.
3.Central shaft position,100% bidirectional bubble tight shut off makes installation acceptable at any direction.
4.Full bore body gives low resistance to flow.
5.No cavities in the flow passage,easy to clean and disinfect for potable water system etc.
6.Liner creates seal with mating flanges so no media is in contact with the valve body.
7.Iso 5211 top flange for easy fitting of actuators.Low operation torques results in easy operation and economical actuator sizing.
8.PTFE lined bearing on shaft allows for low friction & wear.
9.Without using lubricants.
10.Lining bonded to the body to ensure no corrosion between body and lining,longer life,suitable for vacuum service,eg.at the suction side of the pump,suitable for end of line use.
