Location

Caution:

Avoid locations where excessive moisture, corrosive fumes, vibration, or

explosive vapors are present.

Mounting • Mount the linear actuator directly on the valve in locations that clear the maximum

dimensions of the actuator case (see Figure-12).

• Ensure that the valve body is installed correctly. The arrow must point in the direction

of flow. With three-way valves observe stem position (stem up or stem down) for proper

flow characteristics. See Table 3.

• It is preferable that the actuator is mounted above the valve body. This will minimize the

risk of damage to the actuator in the event of condensation or a valve leak. Refer to

Figure-10.

Changing Control Function (proportional units only)

These actuators are equipped with a jumper to control the function of the signal as received.

See Figure-9. Factory setting is for direct acting. Remove cover to change jumper setting.
