Figure 2. Fisher 1052 Actuator with J Mounting Adaptation
W4139-1
The J mounting adaptation permits the actuator to be used for rotary actuation of Fisher keyed-shaft butterfly valve
bodies and other keyed-shaft equipment. This mounting adaptation uses the standard butterfly valve mounting
bracket and provides an output shaft with an attached coupling for keyed equipment shafts. Coupling sizes and torque
limits are listed in table 3. Dimensional information for the mounting bracket and stub shaft coupling is shown in
figures 4, 5, and 7.
Additionally, a top-mounted handwheel can be applied for infrequent service as a manual handwheel actuator. For
more frequent manual operation, a side-mounted handwheel actuator is available. Also, an adjustable up travel stop
can be added to limit the actuator stroke in the upward direction, or an adjustable down travel stop can be added to
limit actuator stroke in the downward direction.
Specifications
Specifications are shown in table 1 for 1051 and 1052 actuators. Specifications for a given 1051 or 1052 actuator as it
originally comes from the factory are stamped on a nameplate attached to the actuator.
