Product Description:
The DKZp/n electric single and double seat regulating valve is the actuator in the DDZ electric unit combination instrument. It receives a unified standard signal of 0-10mADC or 4-20mADC, which is amplified by a servo amplifier to drive the reducer to generate axial thrust, causing the valve core to move accordingly, thus achieving the adjustment of process parameters such as pressure, flow rate, temperature, and liquid level. Electric single seat regulating valve has the characteristics of high flow capacity, low unbalanced force, allowance, and large pressure difference, and is suitable for occasions where leakage requirements are not strict.
