Description Material Performance Product Size Specifications

ZDSF (H) type straight stroke diffluence and confluence of the electric control valve, the valve is equipped with three shunt, combined German import PS series straight stroke electric actuator. The electric actuator in the servo system, no additional servo amplifier, the input control signal (4 20mADC or 1 5VDC) and single-phase power can control the operation, we can adjust the parameters of pressure, flow, temperature, liquid level, the balance valve plug valve plug structure, has good stability, not easy vibration, low noise, allowing the use of pressure, the characteristics of simple connection, widely used for regulating valve flow coefficient, leakage of relatively strict requirements of power, metallurgy, petroleum, chemical industry, environmental protection and other industries of the industrial automatic control system.
