Tube Pinch Valve (Compact & Inert)

This Tube Pinch Valve is a small, specialized valve designed for precise control in applications where avoiding contact between the medium and the internal metal/plastic valve parts is critical. This is achieved by having the medium flow solely through a flexible, replaceable tube, which is externally compressed to achieve shut-off.

Due to its design, it is frequently used in highly sensitive or corrosive applications in analytical instruments, medical devices, and laboratories.

⭐ Key Advantages

Media Isolation: The primary advantage is the complete isolation of the working medium from the valve body, housing, and sealing components. The fluid only contacts the replaceable tubing material (which is selected based on chemical compatibility).
Zero Dead Volume: Because the medium flows straight through an open tube, there are no internal cavities or dead spaces where fluid residue can collect, preventing cross-contamination and bacterial growth.
Easy Maintenance: The internal tube/sleeve, which performs the sealing, can be easily and rapidly changed, simplifying maintenance and decontamination.
Performance: Features a short response time ( $\text{15} - \text{25}\,\text{ms}$ ) for precise, high-speed fluid handling, and has a long service life.
Compactness: Characterized by its small construction size and extremely light weight, making it suitable for integration into portable or densely packed instruments.

💡 Application Focus

This valve is ideal for specialized applications such as:

Medical Diagnostics: $\text{IVD}$ equipment and clinical chemistry analyzers.
Biotechnology: Fermentation and cell culture control.
Chemical Dosing: Precise dispensing of corrosive or high-purity chemicals.
