5 Rack & Pinion Pneumatic Actuators ESR - Models 7901/7921, Spring Return Actuator EDA - Models 7902/7922, Double Acting Actuator Main Features & Characteristics BODY The aluminium body is hard anodized inside and out to provide maximum resistance to abrasion and corrosion. PINION Hardened electroless nickel plated carbon steel shaft is blowout proof and corrosion resistant, teeth are machined for accuracy. ADJUSTMENT STROKE External stainless steel stroke adjustment bolts provide 90 ±5 stroke rotation limits. PISTONS Pistons are specially coated for corrosion resistance with low backlash specially machined teeth. Pistons have a 3-point guiding system to ensure low friction operation along with another integrally machined guide between the pinion and the pistons. POSITION INDICATOR Top mounted position indicator is mechanically configurable for triggering mechanical or inductive limit switches without additional components SPRINGS Springs are positively contained and designed to release all compression before the end cap screws disengage from the body. This safety feature prevents the accidental release of the springs and eliminates the possibility of personal harm. END CAPS End caps are epoxy coated to protect them from environmental corrosion. Double acting and spring return end caps are visibly different in order to allow quick determination of actuator type without having to look at the identification label. TESTING Every actuator is performance tested before being assigned a unique serial number for traceability. ACCESSORIES Mounting of limit switches, positioners, or indicators is accomplished via a NAMUR VDI/VDE 385 mounting arrangement. Additionally, the height of the pinion shaft above the top of the actuator body is identical on all models, thereby simplifying the mounting arrangement for any NAMUR design accessory

6 Bidirectional Travel Stops Econ pneumatic actuators are provided with bidirectional pinion travel stops. Side located stops allow a full ±5 travel adjustment between 85 and 95. These travel stops are designed to absorb the maximum rated torque of the actuator and maximum impact loads associated with recommended travel speeds. Adjustment of the counterclockwise and clockwise rotation limits is accomplished by unscrewing the locking nuts, turning the respective left and right studs to reduce or increase the travel angle and retightening the locking nuts.

15 Rack & Pinion Pneumatic Actuators ESR - Models 7901/7921, Spring Return Actuator EDA - Models 7902/7922, Double Acting Actuator The 20 spring return actuator uses a minimum of two springs and maximum of four springs on each side according to the diagram below. S0 S06 STANDARD 0 and 80 spring return actuators use a minimum of two springs and maximum of seven springs on each side according to the diagram below. S08 S0 S06 S08 S10 S12 S1 STANDARD s 130 to 000 spring return actuators use a minimum of three springs and maximum of seven springs on each side according to the diagram below. (ESR) Spring Combinations for ESR - Models 7901/7921 Pre-stressed springs offer more torque and different options for their positioning. This system allows us to easily fit the necessary torque to close or open the valve, offering a total safety replacement and manipulation. Spring Return Actuators (ESR) use a maximum of seven springs on each side, always using the same type of spring regardless of the spring combination specified. The quantity of springs is identified as follows: Ex: S1 - Where S stands for springs and 1 is the total number of springs assembled in the actuator.
