Output Shaft:
J Double D insert for Type A41
valves
J Optional ISO 5211 square insert,
J Recessed ISO 5211 square drive for P Series
actuators
Dual Stop Adjustment:
J E Series actuators are
furnished with dual stop adjustments (DSA) as a
standard feature.
J P Series actuators provide
dual stops with the use of the “Limit Stop Plate”
(LSP) option. The LSP is mounted between the
actuator and yoke.

Standard: –20 to 79_C (–4 to 175_F) with Nitrile
O-rings
Optional:
High Temperature: –20 to 121_C (–4 to 250_F)
with fluorocarbon O-rings (a ‘‘V” in model
number), or Low Temperature: –40 to 79_C (–40
to 175_F) with EPDM and special lubricant (an

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.
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.
