Description
The Type 1035 actuator is a rack-and-pinion,
pneumatic quarter-turn actuator. The actuator
utilizes a double rack and single pinion design (see
figure 2). The actuator uses three carbon filled PTFE
guide bands, with a balanced piston which prevents
metal-to-metal contact between the pistons and
cylinder wall.
pneumatic quarter-turn actuator. The actuator
utilizes a double rack and single pinion design (see

guide bands, with a balanced piston which prevents
metal-to-metal contact between the pistons and
cylinder wall.
The E Series actuator uses a recessed bushing
inserted into the end of the actuator drive shaft.
Standard recessed double-D bushings match the
Type A41 valve drive shaft. In most applications, the
valve shaft is inserted directly into the recessed
actuator shaft bushing. The P Series actuators
provide a recessed square output shaft for coupling
the actuator to the valve shaft. The Type A41 valve
uses a square-to-double-D drive coupler
construction. Optional couplings are available for
other applications.
