1、 Overview of Electric High Pressure Ball Valve Products
The GYQ941N electric high-pressure ball valve from Shanghai Yuhu Company is composed of a forged steel high-pressure valve body and an electronic angular stroke electric actuator. The electric actuator adopts an integrated structure, which can directly adjust the switch value by inputting 220V power supply. It can also be equipped with a built-in servo module, and can control the operation by inputting control signals (4-20mADC or 1-5VDC) and single-phase power supply. The main components of the electric high-pressure ball valve are forged by professional manufacturers, overcoming the potential defects of cast steel valves and maintaining the structural compressive uniformity under maximum working pressure. Electric high-pressure ball valve is suitable for non corrosive media such as water, oil, and gas, as well as acidic and alkaline corrosive media. Electric high-pressure ball valves are widely used in industries such as chemical, petroleum, natural gas, metallurgy, as well as long-distance natural gas pipelines containing hydrogen sulfide media, high impurities, and severe corrosion.
