Three Point Suspension Systems
Patented Balanced Piston Design
Dual Opposed Piston Design
Three carbon filled Teflon© guide bands provide a low friction bearing surface for piston alignment and rack support. As part of our exclusive suspension system, three equally spaced bearing surfaces are cast into each piston. Air pressure is applied to two piston areas simultaneously to deliver a "balanced force" across the diameter of a common pinion gear.
Elimination of metal-to-metal contact between pistons and cylinder wall reduces friction for outstanding cycle life, smooth piston travel, and maximum power. Transfer of maximum power occurs along the central guide band at the point of rack and pinion contact resulting in even distribution of bearing loads, optimum gear engagement, and elimination of piston tilting. Dual opposed design results in a piston diameter 41% smaller than a single piston design.  Symmetrically balanced center mount construction eliminates undue stress on valve stem, neck, and piping system.

Multiple Spring Concept
Recessed Output Drive
High performance aluminum alloy exclusive to EL-O-MATIC actuators ensures precision rack and pinion engagement. Off-the-shelf availability of multiple spring design means actuators are available for 40, 60, 80, or 100 psig supply air requirements. All units feature a recessed square drive that is precision machined for accurate positioning and is designed to ISO 5211.
Lightweight alloy shaft provides greater corrosion resistance. Equal spring force application to each piston enhances actuator life while conversion from double acting to spring return is simple and safe. A universal adapter is available to provide "direct couple" to valve stem (E25 through E1600 only).
