ZAJV electric V type regulating valve, equipped with DTR series electric actuator, no additional servo amplifier, the input control signal (4-20mADC or 1-5ADC) and single-phase power supply to control operation, the company achieved adjustment of the parameters of pressure and flow, temperature, liquid level etc.. The valve core is provided with a V type notch, and the hard sealing valve seat is relatively rotated to generate the shearing force, which can cut off the fiber and prevent the card from dying. Has the circulation ability, the adjustment precision is high, can adjust the ratio big, the sealing performance is good, the weight is light and so on the characteristic. Suitable for most applications except small diameter, angle type, the three connecting the best products to replace imported products, especially suitable for containing mud and fibrous medium, and suspended solids containing minimal media regulation. Widely used in the industrial process of paper industry, sugar refining, petroleum, chemical, metallurgical and other industries in automatic control system.
