Abstract
In some examples, a pressure regulating valve comprising a pressure chamber, a compressor configured to establish fluid communication with the pressure chamber, a vent valve configured to establish fluid communication with the pressure chamber, a pressure sensor, and a controller. The controller may determine a pressure based on the signal generated by the pressure sensor, and compare a pressure setpoint and the pressure. The controller may be configured to alter the pressure in the pressure chamber based on the comparison between the pressure setpoint and the pressure. For example, the controller may control the compressor to increase the pressure in the pressure chamber and/or control the vent vale to decrease the pressure in the pressure chamber. The altered pressure of the pressure chamber may generate movement of a restricting element within the pressure regulating valve.
