IMI FAS delivered a precision-engineered proportional valve and custom testing system for advanced ventilators - ensuring ultra-fast response, low power use, and verified reliability across every life-critical unit.

Project typeProportional Valve

Challenges with precision, accuracy, repeatability and response time in proportional valves?

A global medical device manufacturer needed a proportional valve for its new ventilator platform—one that could deliver ultra-fast response times, exceptional repeatability, and minimal power consumption. The valve would be in direct contact with patient air, introducing strict safety and compliance demands. Beyond the valve, the customer also required a custom-built production and testing system to ensure consistent, high-performance output at scale.

Precision delivered - IMI Flatprop Meets Trusted Collaboration

IMI FAS applied its deep expertise in proportional valve technology to elevate the Flat Prop EQP to a new level of precision and responsiveness. Key innovations included:

Optimized internal geometry for highly accurate flow control
Integrated filtration and precision press-fit assembly for enhanced reliability
Custom endurance testing protocols simulating 650 million cycles over two years
Real-time signal tracking validation across 100% of production units

The valve’s actual flow response adheres extremely closely to the control signal, minimizing deviation and ensuring consistent performance across all operating conditions. Beyond the product itself, IMI FAS worked hand-in-hand with the customer to co-develop the production and testing equipment needed to manufacture and validate the valve. This included the design of custom laboratory tooling, precision assembly processes, and automated test systems - all built to ensure the highest standards of performance and reliability.

The result is a next-generation valve that combines:
