Actuator Mounting
Use the following steps to connect a valve and actuator that has been ordered separately.
The 1035 E Series is offered with a Double D insert as standard to allow direct coupling to the A41 valve drive shaft. A
few actuator/valve combinations will require the use of an external coupler: E100 with a 1-inch drive shaft, E200 and
E350 with a 1-1/2-inch drive shaft.
P Series applications, the actuators feature an ISO 5211 recessed square drive shaft and requires an external coupler to
engage the valve drive shaft. P Series actuators also require the use of a Limit Stop Plate (LSP) if a Fisher 1080
Declutchable Manual actuator is not being used.
Assemble the bracket, actuator, LSP (if necessary) and valve assembly as follows:
1. Rotate the valve drive shaft to the position necessary to match the valve/actuator operation. See figure 3 for
mounting style codes and positions.
2. Attach the yoke/mounting bracket to the actuator or the LSP (if necessary). Do not fully tighten cap screws at this
time. You will need to align the valve and actuator, or valve, coupler, LSP and actuator before tightening the
mounting screws to the required torque. The 5/8-inch screws should not be used to mount the actuator to the
yoke/mounting bracket. These screws are only to be used for mounting the LSP. Only the 3/4-inch screws are to be
used to mount the actuator to the yoke/mounting actuator.
WARNING
Exceeding any torque requirement may impair the safe operation of this actuator by causing broken or damaged parts.
Refer to table 4 for bolting torque requirements.
The LSP, if used, will also have to be attached to the 1035. Use 4 screws for size P2500/P2505 and 8 screws for size
P4000/P4005. The bolting torque for these 5/8-inch screws will be 10.2 NSm (90 inSlb).
3. The P Series and a few E Series actuator combinations require a coupler. Insert the square end of the coupler into
the drive shaft recess in the actuator, making sure the coupler engages properly.
4. Lower the actuator, and coupling assembly onto the valve, making sure that the male valve stem engages into the
coupler or insert.
a. Secure the mounting bracket to the valve using cap screws and lock washers provided in the mounting kit.
b. At this time, make sure that the actuator is in the operation mode desired, and that the valve is in the correct
position required for your application.
5. For E Series actuators with A41 valves, insert the valve drive shaft end (double-D) into the recessed insert.
6. Align the valve shaft with the actuator drive shaft by changing the positioning on the mounting bracket between
them.
