This three-position cylinder is a fixed position device when controlled by a four-way, three-position, exhaust-centered, 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 1″ (25.4 mm) on each side of the center position, making a total piston rod travel of 2″ (50.8 mm). External envelope dimensions of the cylinder do not change, but shorter strokes are available in increments of 1/16″ (1.59 mm) for each position. The model number of the cylinder and the model number of the piston stop (13A) will have identical four-digit suffix. The first digit denotes the stroke in inches: the last three digit show the stroke in thousandths of an inch.
