Electric Motor Operated Valve Actuators

Rotork s own pakscan system offers advanced actuator network control similar to network control.

Electric motor operated valve actuators.

Due to the large size of the valve actuator an electric motor is needed to open or close a valve. Smart bettis and eim electric actuators over 65 years of field service all over the world in oil and gas water and wastewater marine power generation refineries marine and chemical plants emerson s bettis and eim electric actuators have become the industry standard in valve control. Motor operated valves are generally large valves used in different kinds of operations. Limit switches de energize the electric motor when the valve has reached a specific position.

Most electric motor actuators are equipped with limit switches torque limiters or both. Electric actuator ranges also include the awt for simplified control duties rom rompak and q direct drive actuators for small quarter turn valves. Actuator is a driving device capable of providing linear or rotary motion which works under a certain control signal. Motors are built in accordance with industry standards and are available to suit multiple speeds and voltages.

Electric motor actuator valve traveling nut and worm gear actuators are specifically designed to work with a variety of electric motor actuator products as specified by users and engineers. The clutch and clutch lever disconnects the electric motor from the gear assembly and allows the valve to be operated manually with the handwheel. Also are called electric valve actuator actuated valve motor operated valve mov valve motorized valve etc.
