PNEUMATIC ACTUATORS :
El-O-Matic Pneumatic actuators** are powerful and compact double rack and pinion units for use with ball, butterfly, and plug valves, and any device requiring accurate and dependable quarter-turn rotary motion.
The use of high-grade steel and aluminum components, together with El-O-Matic’s patented 3-point piston support, provides a tough, reliable unit for the automation of today’s high-performance industrial valves. Modern synthetic bearings ensure no metallic contact between moving components.
Spring return actuators incorporate the multiple spring concept for maximum flexibility; they are also “field reversible.” Safety features include an anti-blowout spindle and a spring retaining system that ensures no spring tension on disassembly.
A wide range of control options are available to cover every industrial application.
*‘E’ Series actuators* incorporate a body of cast aluminum and have pistons where the rack teeth are precision-machined onto the aluminum casting. Spring return versions have a maximum of 6 springs (3 in each end cap), assembled as a concentric stack.
*‘P’ Series actuators* cover the large end of the torque range. These incorporate a body of cast aluminum and use steel for the rack and pinion drive. Spring return versions have a maximum of 14 springs (7 in each end cap), assembled within a hexagon pattern.
All actuators have mounting flanges and drives to ISO 5211. Mounting kits can be provided for most of the world’s quarter-turn valves.
