ZDSG type straight travel electric control valve has simple structure, small flow resistance, circulation larger than other valves with diameter, no leakage, can be used for adjusting high viscosity and suspended particles flow, according to the different diaphragm material (rubber or PTFE) applies to adjust alkali, strong corrosive medium. Composed by PSL series electric actuators. Electric actuators with servo system, without equipping the amplifier, have input control signal (4-1-20mA or 5VDC) and single phase can control operation, to achieve the regulation of pressure, flow, temperature, liquid level and other parameters.
