Cordis high resolution electronic proportional pressure controls

Precise, linear pressure control within a closed-loop system with ultra-high resolution and repeatability

The Clippard Cordis is a revolutionary microcontroller primed for escape velocity from a proportional control market that has grown stagnant. Built with the highest quality Clippard 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, the Cordis electronic pressure controls (EPC) utilize the proven EVP and DVP lines of 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, 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 atmosphere. Once a command is increased, the inlet valve opens up to allow supply pressure to pass over the sensor element which provides an active feedback for the microcontroller to satisfy the set point in the process. If at any point the sensor detects a value higher than the set point, the exhaust valve will modulate open to vent off the excess pressure to maintain a stable and accurate control pressure in the process.

  • Smooth linear control
  • Integrated internal or external sensor feedback
  • Static or dynamic applications with the same proportional control
  • Proportional fill and bleed control
  • No integral bleed required

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