Function:

        This is a 4 ported 4 Way Directional Control Valve used to move cylinders or actuators.  Supply pressure must be supplied to the inlet port.  The outlet ports are on the adjacent sides and are connected to each side of a cylinder or actuator.  The pressure will hold the cylinder in one position while the other side of the cylinder is exhausted.  When the lever is rotated in the opposite direction, air will go to the opposite side of the cylinder while exhausting the side that was pressurized.  This causes the cylinder to shift (or extend).  Mufflers may be added to the exhaust ports to quiet the air exhausting.  Adjustable Exhaust restrictors may be used to in the exhaust ports to control the speed of the cylinder.  If flow controls are used, they should always be placed in the lines between the cylinder and the outlet ports and control the air flow as it exhausts from the cylinder.
