E&P Series Pneumatic Rack and Pinion Rotary Actuators Outstanding Performance Under All Types of Continuous Process Conditions For applications involving extreme temperature ranges or corrosive chemicals, to periodic opening or closing of a valve or hundreds of cycles 24 hours a day, pneumatic actuators are required to operate flawlessly under all types of continuous process conditions. EL-O-MATIC E&P Series Pneumatic Actuators offer the high quality and reliable performance needed to keep your process up and running with little or no process downtime and lost revenue due to shutdown....

Three Point Suspension System Dual Opposed, Patented Balanced Piston Design Piston guide bands provide a low friction bearing surface for piston alignment and rack support Elimination of metal-tometal contact between pistons and cylinder wall reduces friction for outstanding cycle life, smooth piston travel, and maximum power High Quality Features Designed to Provide High Cycle, Trouble-Free Life Removable “Splined” Drive Inserts “Splined” Alloy 70-75 shaft has changeable drive inserts for universal mounting to a wide range of valves without the need for brackets or couplings Drive inserts...

“splined” drive inserts (left) NAMUR shaft and air supply connections (right) Safe In-Field Operation with Minimal Maintenance or Downtime E&P Series Pneumatic Rotary Actuators are available in double acting or spring return models and are relatively lightweight due to their compact rack and pinion construction. They are designed so that there are no external moving parts except for a topshaft or a position indicator. This makes them safe, easy to install, and keeps maintenance to a minimum. Both E&P Series spring return actuators are also inherently “fail safe”. In the event of a sudden...

A Complete Choice of Accessories for Advanced Monitoring and Control Applications Limit Switch Boxes HD To signal the open/closed position of the valve– usually in on/off control applications. Standard unit contains two SPDT snap-acting switches that are independently adjustable. CSA Explosion-proof approval, Class I and II, Div. I Groups ABCD and EFG, NEMA 4. Solenoid For actuator control via an electrical signal. Manual Override To open and close the valve manually. Breather Block To prevent contaminants from entering a spring return actuator. 180° Actuation Extended rotation for...

Available Models and Sizing Data E&P Series Pneumatic Rotary Actuators are available in twelve (12) single acting and twelve (12) double acting models. 180° Dual Stroke Adjustment (DSA), Caustic Soda Resistant (CSR) high or low temperature and fast-acting models are also available. Complete sizing data for all major valve manufacturers is on file and available from EL-O-MATIC’s in-house database to ensure proper selection of the right actuator for the right valve. Operating Pressure (90° models) 40 to 120 psig (spring return) 20 to 120 psig (double acting) (180° models) 80 psig max....
