Fluid metering valve

A flow control valve system comprising:

• a pilot stage valve;
• an hydraulic stage valve in fluid communication with said pilot stage valve;
• said hydraulic stage valve comprising a valve member movably mounted in a valve chamber along a valve axis, and adapted to be moved along said valve axis to selectively meter fluid flow in a flow path from at least one inlet port defined between said valve member and said valve chamber and at least one outlet port defined between said valve member and said valve chamber;
• said hydraulic stage valve comprising at least two variable-sized orifices defined between said valve member and said valve chamber and disposed in said flow path between said inlet port and said outlet port;
• an upstream pressure sensor;
• a downstream pressure sensor;
• a fluid temperature sensor;
• a position sensor configured to sense a linear position of said valve member relative to said valve chamber;
• a controller that receives input from said upstream pressure sensor, said downstream pressure sensor, said fluid temperature sensor and said position sensor;
• and
• said controller configured to provide a control signal to said pilot stage valve as a function of said input from said upstream pressure sensor, said downstream pressure sensor, said fluid temperature sensor and said position sensor.
