Engineered for Critical Fluid Control Applications
Every fluid handling application has unique performance requirements. Whether you’re designing a bioreactor system, automating a laboratory process, or developing a pharmaceutical manufacturing solution, selecting the right fluid control technology is essential to achieving accurate, repeatable results.
Resolution Air proportional pinch valves provide continuous, high-resolution flow control while maintaining complete isolation between the valve mechanism and the process fluid. This makes them well suited for applications where precision, sterility, and system reliability are critical.
Fluid Control Requirements Vary by Application
The right valve configuration depends on the realities of the system it will operate in: flow range, tubing size and material, control method, sterility requirements, and operating conditions.
In some systems, the priority is fine control at low flow rates. In others, it is maintaining consistent flow through larger tubing, supporting automation, or protecting the fluid path from contamination. The application is what determines which valve configuration will perform reliably.

Why Engineers Choose Proportional Pinch Valves
Proportional pinch valves are used in demanding fluid control applications because they regulate flow by compressing flexible tubing rather than exposing the fluid to internal valve components.
This approach offers several advantages:
- Complete isolation of the process fluid
- High-resolution proportional flow control
- Reduced contamination risk
- Repeatable fluid metering
- Compatibility with automated control systems
These capabilities make proportional pinch valves well suited for sanitary and precision fluid handling applications.
