The ProValve 200 is an electronic control module for use with proportional solenoid valves in a closed loop system. The integrated PID controller monitors the process feedback and adjusts the current to the solenoids of the valve to achieve the desired position. This closed loop approach significantly simplifies system level control. The module includes indicators on the front panel to provide an overview of the operating status. System configuration is accomplished through a convenient remote terminal. All settings are stored in permanent memory within the unit. The unit is housed in an attractive, compact enclosure.
