Abstract
A fluid control device is disclosed that is configured to vent pilot volume through an exhaust port or exhaust passageway (140) integrated into the fluid control device. The fluid control device has a fluidic switch (112) configured to switch a pilot volume into the exhaust port or exhaust passageway (140) when a signal port or signal passageway (114) is de-pressurized. The fluidic switch (112) couples the signal port or signal passageway (114) to the pilot volume when the signal port or signal passageway (114) is pressurized.
