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.

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 connecting device for sealingly connecting together a pair of modular compressed air conditioning units, for example a filter and a lubricator, comprises a generally rectangular clamp adapted to engage a pair of ported flanges formed respectively on the units to be connected so as to urge the units into fluid-tight communication with one another via an intermediate ported spacer retaining O-ring seals. One side of the rectangular clamp is pivotally mounted so that it can be pivoted out of its operative position to permit reception of the flanges into the clamp and then pivoted back into its operative position in which it can be releasably locked by tightening a bolt. The device may be unitary in nature, i.e. has no separate parts that might otherwise get lost, and is simple to manufacture and manipulate.
