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

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

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.
