Known for reliability, innovation and focus on miniature pneumatics, Clippard’s new Cordis controls 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.
The Cordis is adaptable to a variety of sensors that can close the loop around not only pressure, but vacuum or flow.
• Smooth linear control
• Integrated internal or external sensor feedback
• Multiple flow configurations
• Static or dynamic applications with the same proportional control
• Proportional fill and bleed control
• Customizable pressure ranges and mounting options
