1、 Overview of Electric Cut off Ball Valve Products
The ZAJO electric cut-off ball valve from Shanghai Yuhu Company adopts an O-core structure, so it is also known as an electric O-type ball valve. The electric cut-off ball valve has the characteristics of compact structure, small volume, light weight, close distance between the valve seat and the end face flange, less material retention, and superior sealing performance. Electric switch ball valve is suitable for situations where two positions are cut off. The connection between the valve and the actuator is direct, and the electric actuator does not need to be equipped with a servo amplifier. It can be controlled by inputting 220VAC power supply. Electric cut-off ball valves have the advantages of simple wiring, compact structure, small size, light weight, low resistance, stable and reliable action. Usually suitable for occasions with strict sealing requirements, electric O-ring ball valves and electric cut-off ball valves are widely used in automatic control of industries such as chemical, petroleum, pharmaceutical, and light industry.
