Electric valve actuators mount on valves which, in response to a signal, automatically move to a desired position using an outside power source. Single-phase or three-phase AC or DC motors drive a combination of gears to generate the desired torque level.
Electric valve actuators mount on valves which, in response to a signal, automatically move to a desired position using an outside power source. Single-phase or three-phase AC or DC motors drive a combination of gears to generate the desired torque level. Electric valve actuators are the most popular actuator used due to their high level of precision and their fast response time.
There are two basic types of electric valve actuators: rotary and linear. Each type of actuator uses special valves.
Rotary electric valve actuators are used with ball, plug, and butterfly valves that rotate a quarter-turn or more from open to close. Rotary electric valve actuators are used in the electric power industry, high-power switching gears, and packaging applications.
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.
Pneumatic Actuator positions a control valve by transmitting its motion through the stem. It has Positioner that regulates the supply air pressure. Pneumatic actuators, are the products used to provide linear or rotary motion and force to automated systems
Pneumatic operated valves are one of an array of components responsible for controlling the pressure, rate, and amount of air as it moves through a pneumatic system. Air Operated is a type of power operated valve that uses air pressure against a piston or diaphragm to produce linear or circular movement to operate a valve. Types are 2-way, 3-way and 4-way. The 2 way air-operated valves can be either normally closed or normally opened
