Abstract

A two-stage fluid control valve includes a first stage electronically switchable, bi-stable two-port valve movable between an open position and a leak-free closed position, and a second stage microvalve configured to control the flow of fluid through a fluid outlet of the two-stage fluid control valve when the first stage electronically switchable, bi-stable two-port valve is in the open position. The electronically switchable, bi-stable two-port valve is disposed between the second stage microvalve and a fluid inlet of the two-stage fluid control valve.
