Electric three-way thread ball valve has two internal and four sealed structure, the spool channel L-type and T-type two structural forms, using the control spool rotation angle, change the connection status of the spool bore and the mouth of the pipe, can be realized on three different combinations of control manifold. Electric internal threaded tee ball flow capacity, can control the gas, liquid, steam, more suitable for the control of high viscosity, fibrous particulate fluids. Also suitable for sealing requirements more stringent occasions.
