Introduction: The Automax SX-Series stainless steel actuators are a corrosion resistant rack and pinion actuator suitable for use in corrosive environments. The SX Series stainless steel actuator is well suited for automating butterfly, ball, and plug valves in harsh, corrosive environments. All external components of the actuator are 300 series stainless steel which enables the actuator to withstand corrosive environments typically found in chemical and petrochemical plants, as well as other locations. Optional APS2 or stainless steel pistons and springs extend the corrosion protection to internal components. The SX-Series stainless steel actuator is ideal for the most demanding applications, including chemical processing, pulp and paper, marine and offshore, food and beverage, and nuclear applications.

Features:

1. NAMUR Mounting. The SX-Series stainless steel actuator has NAMUR mounting patterns which allows for the direct mounting of both accessories and controls. The use of sandwich NAMUR mounted controls with the Automax SX-Series stainless steel actuator allows for a compact design requiring no tubing or fittings. The NAMUR mounting pattern maintains a lower mounting profile for accessories such as limit switches and positioners.

2. Corrosion Resistant Materials. All external components are 300 series stainless steel. Optional stainless steel pistons and springs are available for internal corrosion resistance. Optional stainless steel APS2 air purge module is available for standard stainless steel spring return actuators.

3. Bi-directional Travel Stops. Travel stops allow for adjustment of the clockwise and counterclockwise positions. The unique travel stops allow for 5° overtravel in each position and unlimited undertravel adjustment in each direction.

4. Field Reversible Action. Field reversible action accomplished by simply rotating the pistons 180°.

5. Interchangeability. One design for spring return and double acting actuators allows for maximum interchangeability.

6. Concentric Nested Spring Design. Significantly reduces the number of parts and allows for maximum spring gage and cycle life.

7. Broad Size Range. Broad size range offers optimum actuator sizing. 8. ISO Valve Mounting Pattern.
