Clippard Releases Cordis HP500 High Pressure EPR

The new Cordis HP500 is a higher pressure Cordis unit that allows for calibration ranges up to 500 psi and supply pressure as high as 550 psi.

The HP500 is a closed-loop pressure control valve system designed to maintain a steady and repeatable downstream pressure under static conditions. It uses a microcontroller, integrated pressure sensor, and two Clippard EV electronic 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 HP500 pressure regulator is adaptable to a variety of sensors that can close the loop around pressure.
