摘要：
A pressure and flow control system includes a hydraulically-controlled component, a pilot valve, and a regulating valve. The pilot valve is configured to produce a pilot signal and includes a first valve, which is a MEMS microvalve. The regulating valve is in fluid communication with the pilot valve, and is configured to receive the pilot signal. The regulating valve is further configured to output a control signal, which controls the hydraulically-controlled component.
