Four ported ASCO valves are generally used to operate double acting cylinders or actuators.  They have four or five pipe connections: One pressure inlet, Two cylinder ports providing pressure to the double acting cylinder or actuator, One or Two outlets to exhaust pressure from the cylinders.  In a de-energized position, pressure is connected to one cylinder port; the other port is connected to the exhaust.  In an energized position, pressure and exhaust are reversed.
