Cordis Proportional Pressure Regulator

The Clippard Cordis is a microcontroller primed for escape velocity from a proportional control market that has grown stagnant. Built with the highest quality Clippard EVP and DVP proportional valves at its heart, the Cordis is designed to outperform the competition in every way. With unparalleled performance and flexibility not possible with current analog proportional controllers, the Cordis makes everything from calibration to sensor variety acceptance to future development opportunities more accessible and less complicated. The future of proportional pressure control has arrived, and it's digital.

Known for reliability, innovation, and focus on miniature pneumatics, Clippard's Cordis controls utilize the proven EVP and DVP lines of electronic proportional valves allowing for steady, repeatable downstream pressure as demand or processes change. The result, a precise linear pressure control within a closed-loop system with ultra high resolution and repeatability.

The Cordis uses a microcontroller, an integrated pressure sensor, and two Clippard proportional valves. The inlet valve is connected to the moderately regulated supply pressure and the exhaust valve is connected to a port that vents excess pressure to the atmosphere. Once a command is increased, the inlet valve opens up to allow supply pressure to pass over the sensor element which provides active feedback for this microcontroller to satisfy the set point in the process. If at any point the sensor detects a value higher than the setpoint, the exhaust valve will modulate open to vent off the excess pressure to maintain a stable and accurate control pressure in the process.

The Cordis is adaptable to a variety of sensors that can close the loop around not only pressure but vacuum or flow as well.
