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.

Available in 24 double acting and spring return models from 40 to 120 psig air supply, E & P Series Pneumatic Actuators feature a compact, dual opposed, patented balanced piston design and guide band suspension system for optimum performance and long service life.

NAMUR, VDI/VDE 3845 solenoid, positioner, switch mounting, and a splined alloy 70-75 drive shaft with removable drive inserts provide universal accessory and valve mounting. Dual stroke adjustment is also offered on all E Series actuator models.

Integrated control options include manual override, PosiFlex" positioning system, limit switches, solenoid valves, and breather blocks. Special actuator options may be supplied upon application.

N/A 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.

Typical Applications

    E & P Series Pneumatic Rotary Actuators can be used with ball, plug, or butterfly valves for on/off to continuous process control.

    While choice of a particular actuator type depends in part upon die application, the most important selection criteria remains torque. E & P Series Actuators cover a torque range from 80 to 40000 lb.in.

    Special versions are also available for offshore and hygienic applications and can be operated by gas or oil.

Standards

    E & P Series Pneumatic Rotary Actuators are manufactured in accordance with ISO 9001 and also comply with the following international standards:
  • NAMUR, VDI/VDE 3845
  • DIN 3337
  • ISO 5211

Accessories

N/A A Complete Choice of Accessories for Advanced Monitoring and Control Applications
