Output Shaft: J Double D insert for 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.
Supply Pressure (1) (Operating Pressure)
2.8 to 8.3 bar (40 to 120 psig) for both double acting
and spring return actuators
Temperature Range (1)
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 “LT” in model number)
Performance Characteristics
See tables 2 and 3
Rotation for Code A Construction
Rotation is counterclockwise with port “A”
pressurized with standard code A construction.

Description
The 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 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 A41 valve uses a square-to-double-D drive coupler construction. Optional couplings
are available for other applications.
