ZAJV electronic electric V-type regulating ball valve is equipped with LKR series electric actuator. It does not need to be equipped with servo amplifier. It can control the operation with input control signal (4-20mADC or 1-5ADC) and single-phase power supply to realize the adjustment of pressure, flow, temperature, liquid level and other parameters. There is a V-shaped cut on the valve core, and the relative rotation of the hard seal valve seat generates shearing force, which can cut the fiber and prevent the card from being stuck. The electric V-type adjusting ball valve has the characteristics of circulation capacity, high adjustment accuracy, large adjustable ratio, good sealing performance and light weight. Electric V-type regulating ball valve is suitable for most occasions except small diameter, angle type and three-way connection. It is an ideal product to replace imported products, especially suitable for mud and fibrous media, as well as the regulation of medium containing small suspended solids. Widely used in paper industry, sugar, petroleum, chemical industry, metallurgy and other industries of industrial process automatic control system.
