ZDSM series straight stroke electric control valve sleeve, the sleeve valve equipped with imported German PS series 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 etc.. The balance valve plug valve plug structure, has good stability, not easy to produce vibration, low noise, small sensitivity allows the use of a large pressure difference, simple connection, widely used for flow coefficient, leakage of relatively strict requirements of power, metallurgy, petroleum, chemical industry, light industry and industrial automatic control system.
