Spool Design, In Line Mounting

Three position spool valves are used mostly to position cylinders. Valves with all ports open in the center position allow the cylinder piston rod to move freely, while valves with all ports closed in the center position will hold the cylinder in the desired position when no pilot pressure is present. A third type keeps line pressure on both sides of the cylinder piston.

Pneumatically actuated spool valves are available in 1/8 and 1/4 port sizes and require a minimum of 35 PSI operating pressure. Valves can be mounted with through body holes or assembled on manifolds.

Pilot port size (for actuation): 1/8 for all size valves.

Operating pressure range 35 to 145 PSI. Actuation force (pilot pressure): 35 PSI minimum.

Mounting via 4 through body holes 3/16? Dia.

For valve specifications see appendix. See accessory section for manifolds if required. For detail dimensions contact factory.
