LPA11 Flange Ball Valve
The sphere of the ball valve can rotate 90 degrees,which passes the axis by a circular hole.When the sphere rotates 90 degrees,sphere surface presents in the inlet and oulet to shut off fluid.Whereas the hole presents for medium.Cavity of sphere provides for the medium with the flow channel of small resistance and full port.The pneumatic actuator can make the valve close tightly and immediately through rotating 90 degrees.Besides the direct connection of the actuator to the valve body reduces the probability of failure.The pipeline of flange connection can maintain good sealing performance and is convenient for maintenance and pipe sealing .

■Fire prevention and anti-static design.
■Valve rob explosion-proof device.
■Pressure balanced hole on sphere.
■Double stem stuffing and pressure plate-type shrapnel device.
