1、 Overview of Electric Regulating Ball Valve Products
The ZAJQ electric regulating ball valve from Shanghai Yuhu Company is suitable for situations where two positions are cut off and adjusted. The connection between the ball valve and the actuator adopts a direct connection method. The electric actuator has a built-in servo system and does not require a separate servo amplifier. It can be controlled by inputting a 4-20mA signal and a 220VAC power supply. Electric regulating ball valves have the advantages of simple wiring, compact structure, small size, light weight, low resistance, stable and reliable action, etc. Electric regulating ball valves are commonly used in applications with strict sealing requirements. In addition to controlling gas, liquid, and steam media, they are also suitable for controlling sewage and media containing fibrous impurities. They are widely used in various fields such as petroleum, chemical, metallurgical, light industry, papermaking, power plants, and refrigeration. Electric regulating ball valve is an important type of valve, widely used in fields such as petrochemicals and long-distance pipelines. The closing element of a ball valve is a ball (or partial ball) with a hole, which rotates with the valve stem to open or close the valve. The electrically adjustable ball valve can be fully closed and opened by rotating 90 °. Compared with gate valves and globe valves of the same specifications, ball valves have smaller volume and lighter weight, making them easier to install pipelines.
