Fisher 1061 Piston Actuators
The 1061 pneumatic rotary actuators are
double-acting piston actuators that provide reliable
operation for the valves in this flier.
The 1061 can be used with a two-position control
signal for on-off operation or with a valve controller
or positioner for throttling operation.
These actuators feature single-joint linkage with
splined-and-clamped levers for minimum lost motion
and high control accuracy.
The actuator-valve linkage is completely enclosed
for safety, yet the packing adjustment is accessible
without removing any parts.
Specifications . . . Refer to the table below and the
actuator selection tables.
