Product features

The electric flanged ball valve is composed of a flanged ball valve equipped with an electric actuator. It relies on the power drive to operate the opening and closing of the valve and adjust the size of the medium. According to the sealing structure, it can be divided into soft seal and metal hard seal, which are suitable for different working conditions and media. Since the opening and closing parts of the electric flanged ball valve are a round sphere with holes, when the valve is opened, the channel of the valve body and the pipeline form a large diameter, which can allow the medium to flow through the port without loss. Gu is especially suitable for the field where the medium is viscous, containing particles and fibers, and is widely used in petroleum, chemical industry, metallurgy, light industry, paper making, power station Refrigeration and other work fields.
Advantages of electric flange ball valve:
 
1. It can be used in the situation of two position on-off control, and can also adjust the percentage of various parameters such as medium flow, pressure and temperature.
2. Explosion proof type shall be selected according to working conditions, or manual handwheel device shall be equipped to realize the function of manually opening and closing valves.
3. The electric flange ball valve has super small flow resistance, large flow capacity, convenient handling and maintenance, excellent sealing performance, and is suitable for various working conditions.
4. Q941H electric ball valve has small size, light weight, large thrust, built-in servo amplifier, convenient operation and high reliability.
5. The electric flanged ball valve can be used in high-pressure and large-diameter occasions to control the medium with high viscosity, fiber and fine particles.
6. The electric actuator is equipped with a built-in servo system. It does not need to be equipped with a servo amplifier. The input and output signals can be 4-20mA and AC380V power supplies to control the operation. The utility model has the advantages of simple connection, compact structure, stable action, etc.
