On Off Modulating Electric Ball Valve , Motorised Ball Valve With Integrated Structure

Electric ball valve , Angular travel actuator,Control style On-Off or modulating

The construction principle of the electric ball valve:

    The electric ball valve is simple in structure, consisting of only a few parts, and the data consumption is low; the volume is small, the weight is light, the installation size is small, the driving torque is small, and the pressure regulating valve. It is easy to operate and agile. It can be quickly opened and closed by rotating 90°, and it also has good flow regulation and closed sealing characteristics. In the application of large and medium caliber, medium and low pressure, electric ball valves are the dominant valve situation. When the electric ball valve is in the fully open position, the thickness of the disc is the only resistance when the medium flows through the valve body. Therefore, the pressure drop generated by the valve is small, so it has a good flow control feature.
    The electric ball valve has two sealing types: a spring seal and a metal seal. Elastomeric sealing valve, the sealing ring can be mounted on the valve body or attached to the periphery of the disc. Valves with metal seals generally have a longer life than elastomer-sealed valves, but it is difficult to achieve a complete seal. Metal seals can accommodate higher operating temperatures and elastomeric seals have temperature limitations. If the electric ball valve is requested to be used as a flow control, it is important to accurately select the size and type of the valve. The construction principle of the electric ball valve is particularly suitable for the manufacture of large diameter valves. Electric ball valves are not only widely used in general industries such as petroleum, gas, chemical, and water disposal, but also used in cooling water systems of thermal power stations.
     Commonly used electric ball valves are two types of clip-on electric ball valves and flange type electric ball valves. The clip type electric ball valve uses a stud bolt to connect the valve between the two pipe flanges. The flange type electric ball valve has a flange on the valve, and the flanges on both ends of the valve are connected to the pipe flange by bolts. The strength performance of the valve refers to the ability of the valve to be subjected to the pressure of the medium. Valves are mechanical products that are subject to internal pressure and must be of sufficient strength and rigidity to ensure long-term use without cracking or deformation.
