THREE-POSITION CYLINDER – SPRING CENTERED

The three-position cylinder is a fixed position device when controlled by a four-way, three-position. exhaust-center, control valve such as the “A” or “D” PILOTAIR® Valve. The cylinder has a wide range of applications, being particularly suited for shifting transmissions and positioning hydraulic valves. It is corrosion-resistant and constructed of lightweight, die-cast, anodized. aluminum heads, pistons and body.

Maximum stroke of the piston rod is one inch on each side of the center position, making a total piston rod travel of two inches. External envelope dimensions of the cylinder do not change, but shorter strokes are available in increments of 1/16·inch for each position. The complete piece number of the cylinder and the piece number of the piston stop will have an identical four-digit suffix. The first digit denotes the stroke in inches; the last . three digits show the stroke in thousandths of an inch.
