ASCO 8320 valves are 3-way valves with three pipe connections and two orifices. When one orifice is open, the other is closed and vice versa. They are commonly used to alternately apply pressure and exhaust pressure from a valve actuator or a single acting cylinder. These valves can be normally closed, normally open or universal.
