For service applications involving scale formation that sets up and “freezes” mating parts, supplementary
recommendations for assembly can be provided by your
Emerson sales office
or Local Business Partner.
Actuator Mounting
Use the appropriate actuator instruction manual, this section of this manual, and figure 8 of this manual when
mounting the actuator or changing actuator styles and positions.
1. To help ensure correct centering of the V‐notch ball (key 3) on the flow ring (key 4 or 28/29), be sure the ball is
closed when mounting the actuator (for applications other than Spring Return Fail‐Open).

2. Clean the valve shaft and actuator lever splines to be sure the actuator lever will slide on easily. Only drive the lever
in if absolutely necessary.
3. Carefully wedge the ball solidly against the actuator‐side bearing to center the ball.
4. Keep the wedge in place while installing the lever, if necessary. Remove the wedge after you have clamped the
actuator lever on the valve shaft and have connected the lever to the actuator piston rod or diaphragm rod.
Determining Mounting Position for Spline Shaft/Lever Type
The actuator can be either right or left‐hand mounted, with the actuator on the right or left side when viewed from
upstream (see figure 8).
For right‐hand mounting (standard)
, the ball will be in the top of the valve body when the valve is open and the shaft is
horizontal. In this position the ball rotates CW to Close.
For left‐hand mounting,
the ball will be in the top of the valve body when the valve is open and the shaft is horizontal.
In this position the ball rotates CCW to Close.
