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.

1. Tightly screw the valve connector on the valve body. Please pay attention to the
direction of the connector.
2. Install the actuator bracket on the valve connector.
3. Insert the U-type connector into the bracket, and lock the connector nut.
4. Lift up the valve stem and put the lock nut and indicator guide onto it, then
rotate the connecting rod of the actuator and let it rotate onto the valve stem.
Use spanner to lock the locknut after adjusted into position.
5. In vertical installations, leave enough head room to unscrew the actuator prior
to servicing the valve body.
6. Wire the unit according to the appropriate Wiring Diagram.

1. The actuator is driven by a reversible synchronous motor with a magnetic
clutch. The motor can provide stable torsion at stopping conditions due to the
magnetic force created by the motor rotor and the magnetic clutch. When
power is taken away, the motor will stop at its current position.
2. The signal of the proportional type actuator controls the clockwise or counter-
clockwise rotation of the motor.
3. EVA2M (EVA3M) actuators can be jumper selected for 0.51, 0.59, 0.67 or 0.75
inch valve strokes. Factory stroke setting is 0.75”.
4. The input control signal is jumper selectable between 0-10V or 4-20 mA DC.
Factory setting is 0-10V DC input mode.
5. Direct (DA) or Reverse (RA) direction operation is also jumper selectable. The
two states are opposite of each other.

The Series EVA2 and EVA3 Electric Actuators are not field serviceable and should
be returned if repair is needed (field repair should not be attempted and may void
warranty). Make sure to cut off power supply when disconnecting the actuator from
the valve. Contact customer service to receive a return goods authorization
number before shipping. Be sure to include a brief description of the problem plus
any relevant application notes.
