Valve Configurations Functions
2 Way Valve Configuration: 2 Position Valve to turn on and off
3 Way Valve Configuration: 2 Position Valve to fully extend single acting cylinder (spring return cylinder)
4 Way Valve Configuration: 2 Position Valve to fully extend and retract double acting cylinder
4 Way Valve Configuration: 3 Position, Closed-Center Valve to stop a double acting cylinder in partial stroke, all ports are shut off
4 Way Valve Configuration: 3 Position, Exhaust-Center Valve to have both cylinder ports open to exhaust such that the cylinder can be extended and retracted manually to facilitate set-up
4 Way Valve Configuration: 3 Position, Pressure-Center Valve to stop a double acting cylinder in partial stroke with pressure on both ends of the cylinder
