Electric actuator motor

And deceleration device to move the executive body of the valve. Typically, electric actuator input signal is a standard current or voltage signal, the output signal is the motor, reverse or stop the three switching signals. Electric actuator moves quickly, fast response, the power of access to convenient, transmission distance and other characteristics.
The electric actuator according to the displacement divided into straight stroke, rotary and multi-turn and other categories can also be divided into two types of proportional, integral input signal and the output of the relationship.
Electric actuator features are as follows
1 electric actuator is generally the valve position detection device to detect the the valve bit (putting displacement or valve shaft angle), therefore, the electric actuator and detection devices position feedback control system has good stability.solenoid valve actuator
Integral electric actuator output displacement and the input signal is proportional to the time integral of the proportional electric actuator output displacement input signal is proportional to.
3 is normally set electric torque brakes, the electric actuator with rapid braking function, can effectively overcome the shortcomings of mechanical brake caused by mechanical wear and tear.
Complex structure of prices is expensive, does not have a pneumatic actuator intrinsically safe, explosion-proof security measures for use in hazardous locations, consider setting.
5 electric actuators supporting the use of the electric servo amplifier the intelligent servo amplifier can also be composed of intelligent electric control valve. Typically, the electric servo amplifier input signal controller output standard 4 ~ 20mA current signal or voltage signal, amplified conversion motor forward, reverse or stop signal. The method can be larger relays, transistors, magnetic amplifier, the microprocessor may also be used for digital processing, in general, on and off times of the amplifier output with the input signal is proportional to
6. Valve position limits can be set to prevent damage to the equipment.steam solenoid valves
