Electric Actuator Valve Types

Position switches are utilized to indicate the open and closed position of the valve.
Electric actuator valve types. Electric actuators include electric motors and solenoid actuated valves. Figure 2 typical electric motor valve actuator. Typically a declutching mechanism and hand wheel are included so that the valve can be operated manually should a power failure occur. Selection of the best actuator type for any application is dependent on many factors including.
The motor operates in both directions and drives the valve stem by means of gear couplings. Electric motors can be used to open close and position a valve manually automatically or semi automatically. There are two main types of actuators one for each of the two main types of valves that require them. Linear electric valve actuators are used with gate globe diaphragm pinch and angle valves that feature a sliding stem that opens or closes the valve.
Linear electric valve actuators are well suited for operating in tight tolerances. They are rotary and linear. More information on rotary and linear motion valves can be found on engineering360 s valve types page. This power source can be electric pneumatic compressed air or hydraulic the flow of oil.
