Abstract

A fluid system includes a controller, a control valve, and a fluid manifold. A first solenoid may be connected to the fluid manifold, the control valve, and/or the controller. A second solenoid may be connected to the fluid manifold, the control valve, and/or the controller. A first pressure sensor may be in fluid communication with an output of the control valve. A second pressure sensor may be in fluid communication with the fluid manifold. The controller may be configured to control operation of the control valve via the first solenoid and the second solenoid according to a first fluid pressure obtained via the first pressure sensor and according to a second fluid pressure obtained via the second pressure sensor.
