Electric Actuator Valve Types

To protect the valve the torque sensing mechanism of the actuator turns off the electric motor when a safe torque level is exceeded.

Electric actuator valve types.

Linear electric valve actuators are well suited for operating in tight tolerances. They are rotary and linear. The motor operates in both directions and drives the valve stem by means of gear couplings. Position switches are utilized to indicate the open and closed position of the valve.

Electric actuators include electric motors and solenoid actuated valves. More information on rotary and linear motion valves can be found on engineering360 s valve types page. Pneumatic actuators provide for automatic or semi automatic valve operation. There are two main types of actuators one for each of the two main types of valves that require them.

Electric motors can be used to open close and position a valve manually automatically or semi automatically. Figure 2 typical electric motor valve actuator. Selection of the best actuator type for any application is dependent on many factors including. This power source can be electric pneumatic compressed air or hydraulic the flow of oil.
