Dwyer-Electric Actuator-Eva

General

The Series EVA Electric Actuators are designed to mount directly onto the Series GV globe valves, creating a complete, low cost, and compact control valve package. Floating or modulating control inputs are

available, and the 24 VAC synchronic motor includes a magnetic clutch to protect the motor in stall conditions. Actuators are ruggedly constructed with a fire-proof ABS housing and robust aluminium bracket.

Features include a visual position indicator and manual override to make this actuator an excellent choice for any size area, large or small.
