Miniature Proportional Pinch Valves for Precision Applications
M Series proportional pinch valves are designed for applications requiring precise, continuous control of fluid flow in a compact form factor. These valves regulate flow by compressing flexible tubing, allowing accurate adjustment without exposing the fluid to internal valve components.
This design enables high-resolution control and repeatable performance while maintaining a fully isolated, contamination-free fluid path.
How M Series Valves Integrate into Fluid Control Systems
M Series valves operate by applying controlled compression to flexible tubing, allowing for continuous adjustment of flow. When paired with a driver or controller, these valves can be integrated into automated systems using standard control signals. This enables precise control of fluid delivery in applications requiring accurate dosing, sampling, or metering.
When M Series Valves Are the Right Choice

- Low-flow fluid metering applications
- Systems requiring high precision and repeatability
- Compact or space-constrained system designs
- Laboratory and analytical applications
- Applications where contamination-free fluid handling is required

M Series vs Other Valve Options
M Series proportional pinch valves provide advantages over traditional on/off valves by enabling continuous flow control rather than binary operation. This allows for more accurate fluid metering and improved repeatability.
Compared to larger valve configurations, M Series valves are optimized for applications where compact size and fine control are the primary requirements.
