Enfield Technologies has introduced the Enfinity System for advanced proportional control. This system comprises Enfield Technologies’ M2 pneumatic control valve and C2 controller. The M2 is an instrument-grade, proportional, directional control pneumatic valve that is designed for high performance. This valve utilizes a specialized linear force motor, as opposed to a traditional proportional solenoid. The M2’s aperture is controlled at a very high speed, allowing the valve to respond quickly to set-point command changes. Enfield Technologies’ C2 is an enclosed high-speed, high-accuracy analog controller with multiple PID and feed forward options. It also includes an intuitive, user-friendly digital LCD/membrane keypad user interface.
