Electric three-way ball valve with HR type, HQ-type angular travel electric actuator, with AC220V, AC380V or DC24V power supply as the driving force, accept industrial automation instrumentation control system input (4-20mA, or 1-5VDC) current signal or voltage signal , You can control the operation, to achieve the proportion of the process medium adjustment or two switching control. Q914 / Q915-type electric three-way ball valve is Yu into the domestic and foreign advanced technology company developed a new electric three-way ball valve. The standard ball core has a L-shaped three-way hole, which can change the relative angle between the core and the pipe to realize different combination control on the three pipelines. The T-shaped hole can play a role of proportioning and is suitable for liquid, gas and steam Medium ratio adjustment and control. Features (1) Electric three-way female ball valve has two and four seal structure, spool hole L-type and T-type structure of two types, the use of control spool rotation angle, change the spool hole and the pipe port connection status , Can achieve different combinations of three branch control. Three-way ball valve flow capacity, can control the gas, liquid, steam, more suitable for controlling the high viscosity, fibrous particles of fluid. Also apply to the more stringent sealing occasions. (2) two seat three-way ball valve seal has the advantages of compact structure, beautiful appearance, good sealing performance, it can achieve the pipeline medium flow switch. It also allows two channels perpendicular to each other to communicate or shut down. (3) The four-seat sealed three-way ball valve is handsome in appearance and compact in structure. It can not only switch the flow of media, but also enable the three channels to communicate with each other. At the same time, any one channel can be closed and the other two channels can communicate with each other. Flexible control of the pipeline is the convergence or diversion of media. (4) T-type spool hole allows the three orthogonal pipes connected to each other or switch, from the shunt or confluence; L-shaped channels to connect two mutually orthogonal pipe. Make another hole cut off, play a role in changing the medium flow.
