READ ALL INSTRUCTIONS CAREFULLY BEFORE BEGINNING. 

INSTALLATION OF E026 & E029/

E030 ACTUATORS ON THE VALVE

SEE DRAWING D3400025 on page 17

THE SILVER SPACER RING THAT COMES WITH THE ACTUATOR MUST BE

ASSEMBLED ON TOP SIDE OF YOKE AS SHOWN ON DRAWING.

1)   Push valve stem down until plug is seated. Note stem location.

2)   Remove stem connector socket head nuts, remove stem 

connector U-bolt.

3)    Install hex jam nut (Item 5) on valve stem. Thread jam nut so 

that one inch of threads are exposed between jam nut and 
top of stem.

4)     Hold jam nut on valve stem and turn the stem adapter (Item 

2) until it bottoms out on the valve stem. Tighten jam nut to 
the bottom of the stem adapter to secure valve stem to stem 
adapter. 

WARNING: THE VALVE STEM SHOULD NEVER BE 
TURNED WHILE THE PLUG IS IN CONTACT WITH 
THE SEAT OTHERWISE THE SEATING SURFACES 
WILL BE DAMAGED VOIDING THE WARRANTY.

5)    Place actuator, spacer ring (Item 3) and yoke locknut 
 

(Item 4) over valve stem and onto bonnet. Watch orientation 
of spacer ring and yoke locknut. Actuator base must rest on 
bonnet. If necessary, use the manual override to raise the 
stem connector (See manual override on page 3).

WARNING: DO NOT FORCE OR TURN THE MANUAL 
OVERRIDE WHEN THE MANUAL OVERRIDE 
BUTTON IS NOT PRESSED. DOING SO MAY CAUSE 
DAMAGE TO THE ACTUATOR GEARS.

6)  Rotate actuator to desired orientation. For the factory default 

actuator position the motor electrical wire end of the actuator 

faces the outlet side of a 2-way valve, common “C” port on a 

3-way mixing valve, and lower “L” port on a 3-way diverting 

valve. Thread yoke locknut onto bonnet and tighted securely. 

Use blunt chisel and hammer for tightening.

7)   Push valve stem down until plug is seated. Refer to position 

noted in Step 1.

8)     While holding the bottom of the stem connector open, use 

the actuator manual override to lower the stem connector 
over the stem adapter (See manual override on page 3). 
Install stem connector U-bolt through stem connector. 
Watch orientation.  The socket head nuts when installed on 
the U-bolt must face away from the electrical wire end of the 
motor.  Install the socket head nuts on the U-bolt.  Evenly 
torque the socket head nuts to 44 in-lbf torque.

WARNING: DO NOT FORCE OR TURN THE MANUAL 
OVERRIDE WHEN THE MANUAL OVERRIDE 
BUTTON IS NOT PRESSED. DOING SO MAY CAUSE 
DAMAGE TO THE ACTUATOR GEARS.

WARNING: THE VALVE STEM SHOULD NEVER BE 
TURNED WHILE THE PLUG IS IN CONTACT WITH 
THE SEAT OTHERWISE THE SEATING SURFACES
