Check Valves and Three-Way Connectors

Check Valves and Three-Way Connectors

Comprising a rotatable valve core mechanism and body, these components require exceptionally tight dimensional tolerances and excellent surface smoothness to prevent fluid leakage.

Technical Challenges:

Achieving airtight ultrasonic welds and smooth valve rotation.

Pressure Resistance and Airtightness

In infusion systems, check valves and three-way connectors often need to withstand pressure generated by infusion pumps or the patient's blood pressure.

Technical Challenges:

The housing must pass high-pressure leak testing, typically withstanding several times its rated pressure without bursting or leaking.
