The Westlock P-10 pneumatic positioner accepts variable pneumatic instrumentation signals (typically between 3 and 15 psig) and regulates the 80-psi air supply to the actuator via a characterized cam, diaphragm and spool. The diaphragm receives an input pressure signal from the controller, which applies force to the spool valve spring causing the spool valve to move. This movement modifies the air pressure to the actuator, permitting the actuator to respond accordingly. The characterized cam transmits the actuator movement to the spool valve.

Standard Features

• Epoxy coated die cast aluminum housing meeting NEMA 4X
• Disc indication within a flat cover
• Split range capability
• Reverse acting capability
• NAMUR mount - no linkage

The Safety Spring option for single acting pneumatic actuators. This option allows the removal of the end caps for maintenance or changing of the fail orientation without the fear of injury due to the stored energy of the springs. We have incorporated a captive spring design (shown as the black, green and yellow items) into the concentric spring pack so that they are contained, and the stored energy remains just that; stored. The Safety Spring option is available for the C79P through the G79P. The output torque of the actuator and actuator dimensions are unaffected with this option.

The Integral travel stop for double and single acting pneumatic actuators. The integral travel stop allows for independent adjustment of the close stroke (0 °) from -2 ° to +4 °, and independent adjustment of the open stroke (90 °) from -4 ° to +2 °; and is available for models C79P through G79 P. This is a factory-installed option. All products that are manufactured have tolerances that must be met. When multiple manufactured products are assembled, the total tolerance for all of the "components" becomes exaggerated. When this occurs, it is possible that the actuator will rotate 90 degrees, but the valve will actually rotate less than 90 degrees. To compensate for this action, the actuator must travel more than 90 degrees so that the valve can travel to its full open and full closed positions. With this in mind, we have developed and now offer the integral travel stop option.
