ZAJV electronic type electric v-type regulating control valves
features
ZAJV electronic type electric v-type regulative control valve, equipped with YHR series electric actuators, without equipped the servo amplifiers, input control signal (4-1-20mADC or 1-5ADC) and single-phase power can control running, to achieve the adjustment of pressure, flow, temperature, liquid level and other parameters. Valve core has V-shaped incision, and hard sealing seat relative rotation produced shear force, can cut the fibre, prevent jammed. It has the circulation ability, high adjustable precision, big adjustable ratio, good sealing, light weight, etc. Applicable to many occasions except small diameter, angle, tee connection, is the best products to replace the imported products, especially suitable for mud and contain fiber dimension, as well as the medium containing small suspended solids medium regulation. It is widely used in industry, sugar, petroleum, chemical, metallurgy and other industries automatic control system.
