Flow Control Valves control air from cylinders.

Models JFC-4 and JFC-5 are combination needle and check valve flow controls used to control air flow from air cylinders. Units control speed at which piston strokes, either while extending or retracting, depending on location in circuit. They allow free flow from inlet to outlet past needle and check valve. In reverse flow, check valve is sealed and flow must pass through metered passage...
