The Series EVA2 and EVA3 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 aluminum bracket. Features include a visual position indicator and manual
override to make this actuator an excellent choice for any size area, large or small.
FEATuRES
