The Clippard Cordis CPC series represents a major shift in the proportional control market, moving from stagnant analog technology to a high-performance digital microcontroller platform. At the heart of the Cordis system are Clippard's legendary EVP and DVP proportional valves, known for their longevity and precision. This combination creates a closed-loop pressure control system that delivers ultra-high resolution and repeatability that analog controllers simply cannot match.

Unmatched Performance and Flexibility

The Cordis is designed for "escape velocity" from the limitations of the current market. By utilizing a digital architecture, it allows for real-time adjustable PID control. This means the system can be fine-tuned for specific application dynamics—whether the volume is large or small, or if the flow requirements are static or highly dynamic. Unlike many competitive units that require an "integral bleed" (a constant leak) to maintain steady pressure, the Cordis maintains stability without wasting gas, making it far more efficient for critical gas handling.

Key Benefits of Digital Regulation

• Smooth Linear Control: Eliminates the "steps" often found in lower-quality digital controls, providing a seamless transition across the entire pressure range.
• Real-Time PID Adjustability: Operators can modify control parameters on the fly to optimize performance for changing system demands.
• Multiple Flow Configurations: Available in various flow sizes to accommodate everything from micro-liter leak testing to high-flow industrial processes.
• Sensor Variety Acceptance: The digital platform can be calibrated to work with a wide range of internal or external pressure sensors, increasing system accessibility.
• Future-Proof Development: As application requirements evolve, the Cordis firmware and hardware can be adapted more easily than fixed analog circuits.

Typical Applications

• Medical Equipment: Precise pressure control for ventilators, anesthesia delivery, and patient monitoring.
• Analytical Instrumentation: Managing carrier gas pressures in gas chromatography (GC) and mass spectrometry.
• Industrial Automation: Controlling tension in web handling, or managing pressure in precision leak testing.
• Aerospace & Defense: High-reliability gas regulation for sensitive electronic cooling or fuel cell systems.
