The pneumatic three-way ball valve produced by our company is composed of angular stroke piston type pneumatic actuator and three-way ball valve, is a rotary cut-off, regulating valves, has the advantages of tight closure, compact structure, light weight, easy maintenance and so on. Pneumatic three-way ball valve can be equipped with a valve positioner input control signal (4-20mADC or 1-5VDC) gas source can control the operation. Can also be equipped with travel limit switches, solenoid valves, pressure reducing valves and 0.4-0.7MPa gas source can be realized switching operation, and send out two pairs of passive contact signals to indicate the valve switch. Two valve seat sealing pneumatic three-way ball valve has a compact structure, beautiful appearance, good sealing performance, it can realize the switching of the medium flow direction in the pipeline, but also to make the two channels perpendicular to each other connected or closed. Four-seat sealed pneumatic three-way ball valve has a beautiful shape, compact and reasonable structure. It can not only realize the switching of the medium flow direction, can also make three channels connected to each other, now can also close any channel, so that the other two channels are connected to flexibly control the combined flow of the medium in the pipeline or shunt. Pneumatic three-way ball valves are suitable for water supply, petrochemical, metallurgy, mining, textile, energy, papermaking, food, steel and other pipeline systems to switch the direction of flow of the medium as well as shunt or mixing of the medium fluid.
