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

Exhaust venting for a fluid control device

An electrical circuit and method for switching an input voltage onto a load by way of an AC control voltage is provided. A voltage magnitude reduction circuit is configured to be driven by the AC control voltage. A rectifier circuit is operably coupled with the voltage magnitude reduction circuit. Also, a voltage limiter circuit is operably coupled with the rectifier circuit, and an energy storage circuit is operably coupled with the voltage limiter circuit. The voltage magnitude reduction circuit, the rectifier circuit, the energy storage circuit and the voltage limiter circuit cooperatively generate a switch control voltage. An electronic switching unit is then configured to switch the input voltage across the load when the switch control voltage is active. In one embodiment, the input voltage is a DC voltage generated by an AC-to-DC voltage converter circuit configured to convert an AC supply voltage to the DC voltage.

AC-to-DC electrical switching circuit

A double solenoid PC board that has a long narrow section extending from the main section is disclosed. The long narrow section has a connector at the tip. The connector at the tip of the long narrow section is configured to mate with or couple to a mating connector on a single solenoid PC board in a double solenoid valve.

Valve with an integrated PC board and connecting bar

A valve island that has the PC board captured in the expansion station is disclosed. The PC board is held into the expansion station by a feature on the PC board that interferes with the inside of the wire-way of the expansion station sub-base.

A valve island that has vented non-active areas is disclosed. The valve island has a plurality of active gas passageways that are coupled together between components. At the junction between the different components the active fluid passageways are surrounded by a sealing surface. The sealing surface essentially surrounds some non-active areas. The non-active areas are vented to the outside air through one or more passageways. The non-active areas may be recessed from the sealing surface.

Valve island with non-active area venting between components

A valve island that has a pilot fluid passageway located on the side of the sub-base is disclosed. The pilot fluid passageway is formed into one side of the sub-base and couples the front end of the sub-base with the back end of the sub-base. A gasket or sealing device may be used to help form a seal around the pilot fluid passageway when the sub-base is joined to a mating part.
