The electric regulating ball is equipped with fosd series actuator. It does not need to be equipped with a servo amplifier. The operation can be controlled by inputting (4-20madc or 1-5vcd) signal and single-phase power supply to realize the adjustment of pressure, flow, temperature, liquid level and other parameters. The core is provided with a V-shaped notch, which generates shear force by relative rotation with the hard seal seat, which can cut the fiber and prevent jamming. It has the characteristics of large circulation capacity, high adjustment precision, large adjustable ratio, good sealing performance and light weight. It is used for most occasions except small caliber, angle type and tee connection, and is the best product to replace imported products, especially for the adjustment of mud and medium containing fiber and medium containing micro solid floating matter. It is widely used in industrial automation control systems such as paper industry, sugar industry, petroleum, chemical industry, metallurgy, air conditioning, fire protection, water supply and drainage.
