wards the spring. If the valve is normally-opennormally-open, fluid flow will be cut off by the pilot line. If the valve is normally-closednormally-closed, the pilot line will cause oil to start flowing. Valves can either be on/off valves with no flow in the middle, or infinitely variable, which means flow will gradually increase

With a regulator positioned after a receiver tank, air from the receiver can expand (flow) through the valve to a point downstream. As pressure after the regulator rises, it is sensed in an internal pilot passage leading to the underside of the piston.
