The Q944F/Q945F electric cryogenic three-way ball valve consists of an angular stroke series intelligent actuator and a three-way ball valve. It is a rotary flow-switching valve with advantages such as tight closure, compact structure, light weight, and easy maintenance. Electric cryogenic three-way ball valves are widely used in the automated control of pipelines carrying corrosive media such as gases, liquids, steam, and oils. The electric three-way ball valve can switch the flow direction of the medium in the pipeline. It can also connect or close two mutually perpendicular channels. The four-seat sealed three-way ball valve has an aesthetically pleasing and compact structure. The electric cryogenic three-way ball valve can not only switch the flow direction of the medium but also connect the three channels. It can also close any channel while connecting the other two, flexibly controlling the merging or splitting of the medium in the pipeline. Therefore, it is called an electric three-way directional ball valve.

Control Method: Electric cryogenic three-way ball valves are available in L-type and T-type, with the media flow direction shown in the diagram below. The L-type electric three-way ball valve is suitable for switching media flow direction, allowing two perpendicular channels to be connected. The T-type electric three-way ball valve is suitable for media diversion, merging, or flow direction switching. The T-type orifice allows three channels to be interconnected or two channels to be connected. Electric three-way ball valves generally use a three-seat structure, but a four-seat structure can also be used according to user requirements.
