Electric three-way ball valve products

Anshan AEN.TECH Q944F / PPL-H electric three-way ball valve is made up of a series of intelligent actuators and three way ball valves. It is a kind of rotary cutting and regulating valve. The electric three-way ball valve has the advantages of close closure, compact structure, light weight, convenient maintenance and so on. Electric three-way regulating ball valve is widely used in pipeline automation control of corrosive medium such as gas, liquid, steam and oil. Two-seat sealed electric three-way ball valve with compact structure, beautiful appearance, good sealing performance. The electric three-way ball valve can realize the switch of the medium flow direction in the pipeline. Two channels that are perpendicular to each other can also be connected or closed. Four-seat sealed three-way ball valve with beautiful shape, compact and reasonable structure. The electric three-way ball valve can not only realize the medium flow direction switching, but also make the three channels connected to each other. At present, the electric three-way ball valve can also close any channel, so that the other two channels can be connected, and flexible control of the combination or shunt of the medium in the pipeline can be achieved

Control mode of electric three-way ball valve

The electric three-way ball valve is divided into L type and T type, and the medium flow direction is shown in the following figure. The L electric three-way ball valve is suitable for the medium flow direction switch, and can make two vertical channels connected to each other. The electric three-way valve is suitable for the distribution of the medium. The confluence or flow direction switch T-hole can make the three channels connected to each other or two of them. The electric three-way ball valve generally adopts the three-seat structure, or it can adopt the four-seat structure according to the user's request.

Electric three-way ball valve product selection

(1) valve body parameters: nominal diameter, working pressure, process media, use occasions, valve body materials and other series of parameters.

(2) actuator parameters: power supply voltage, control mode, Control signal (4-20mAX 1-5V), the mode of action (electric-open, electric-switch) to provide the above technical parameters as detailed as possible to facilitate our company sales and technical personnel for your accurate selection. If there is any doubt. You can call us, and we will do our best to provide you with excellent service
