Single or double-acting cylinders 4-Way 3-Position (closed center) and (tandem center) manual valves with Posi-Check® Application: Single or double-acting cylinders. When used with single-acting cylinders, one port must be plugged. For double-acting cylinders, either port can be used to “advance” or “return.” Actuation: Lever-operated, detent positioned. Functions: The 9508 provides “advance,” “hold” and “return” positions with all ports blocked (closed center) in the “hold” position. The 9509 has “advance,” “hold” and “return” with tandem center (cylinder ports are blocked, pump remains running). Both valves have Posi-Check® feature to guard against pressure loss when shifting from “advance” to “hold.”
