Abstract
An isolation valve has an electrically-actuated solenoid valve, at least one port having a port extension, and a sensor assembly coupled to the port extension. The sensor assembly includes a printed circuit board, an integrated circuit disposed on the circuit board, and at least one pressure sensor coupled to the port extension to measure a vapor pressure in the port extension. In one embodiment, a single sensor assembly can monitor pressure at two or more ports. By integrating the sensor assembly into the isolation valve, the valve has a compact assembly that is easy to install in a vapor control system.
