The three-way pneumatic ball valve is a rotary three-way valve with reversing and cutting functions. There are mainly L-shaped and T-shaped structures. The L-shaped three vent pneumatic ball valve is used to switch the flow direction of the medium. It can connect the main pipeline and the other two pipelines separately and switch them at will. T-shaped three vent pneumatic ball valve can be used for the diversion and confluence of three pipelines, and any two of the three pipelines can be connected according to the working conditions. The specific control mode is as follows. In actual use, one three-way valve can replace more than two two-way valves, which not only saves installation space, but also saves costs, making the operation more convenient. Different valve bodies and sealing materials can be selected according to user needs. There are two installation methods: flange and thread. In order to facilitate the use of users, the three vent ball valve can also be equipped with electric or pneumatic actuators, which are electric three vent ball valve and pneumatic three vent ball valve, and can be used for remote automatic control.
