Valve bank and smart control valve

A valve bank for controlling flow of a fluid, the valve bank comprising:

• a fluid manifold;
• a plurality of modular control valves fluidly connected to the fluid manifold;
• and
• a sensor configured to sense a characteristic associated with a function of the valve bank;
• wherein:
• at least one modular control valve of the plurality of modular control valves includes:
• (i) a valve body adapted for fluid connection to the fluid manifold, the valve body having an inlet passage, an outlet passage, and a fluid flow path extending between the inlet and outlet passages;
• (ii) a valve member movable in the fluid flow path and relative to the valve body to control flow of the fluid through the valve body;
• an onboard electronic controller is operably mounted to the valve bank;
• and
• at least one actuator is operably connected to the onboard electronic controller;
• the at least one actuator being configured to control movement of the valve member of the at least one modular control valve in response to commands from the onboard electronic controller;
• wherein the onboard electronic controller is operably coupled to the sensor and is configured to receive information from the sensor that corresponds with the characteristic, wherein information received from the sensor comprises pressure traces, wherein the onboard electronic controller is configured to identify at least one event of the at least one modular control valve based on the pressure traces, wherein the onboard electronic controller is further configured to compare a pressure and a time at the at least one identified event to a normal value of pressure and time for the at least one identified event previously stored in the onboard electronic controller, wherein the onboard electronic controller is further configured to transmit results of the comparison to an upper-level programmable control logic controller, and
• wherein the onboard electronic controller being configured to control movement of the valve member via the at least one actuator based upon the information received from the sensor.
