Proportional Pinch Valves for Precision Fluid Control
Proportional pinch valves regulate fluid flow by compressing flexible tubing rather than contacting the fluid directly. This approach enables precise, continuous control while maintaining a fully isolated fluid path.
These valves are commonly used in applications requiring accurate fluid metering, repeatable performance, and contamination-free operation. Their non-contact design makes them well-suited for bioprocessing and laboratory systems.
Selecting the Right Valve for Your Application
Resolution Air offers two primary proportional pinch valve configurations to support a range of system requirements.
M Series Miniature Proportional Pinch Valves
Compact proportional pinch valves designed for applications requiring precise control in a small form factor. Commonly used in low-flow systems where accuracy and repeatability are critical.
Key Characteristics:
- Compact design for space-constrained systems
- High-resolution control for precise fluid metering
- Suitable for laboratory applications
- Best for low-flow, high-precision applications
- Fine control and repeatability
H Series Hybrid Proportional Pinch Valves
Designed for applications requiring higher pinch force and support for larger tubing sizes. Suited for systems with greater flow requirements or more demanding operating conditions.
Key Characteristics:
- Higher force capability for larger tubing
- Increased flow capacity
- Designed for more demanding fluid control applications
- Best for higher flow and larger tubing sizes
- Broader operating range
Drivers & Controllers for Proportional Pinch Valves
Drivers and controllers are used to operate proportional pinch valves within automated systems. These components enable precise control of valve position using standard input signals, supporting integration with a wide range of control systems.
Applications for Proportional Pinch Valves
- Bioprocessing fluid control
- Chemical dosing and dispensing
- Fluid metering systems
- Laboratory diagnostics and automation
