Check Valves & 3-way Stopcocks

Check Valves & 3-way Stopcocks

Includes a rotatable valve core mechanism and main body, with extremely high requirements for dimensional tolerance and surface smoothness to prevent fluid leakage.

Technical Barriers：

Airtightness of ultrasonic welding and smooth valve rotation.

Sealing & Burst Pressure

Check valves and three-way stopcocks in infusion systems often need to withstand pressure generated by infusion pumps or the patient’s blood pressure.

Technical Barriers：

The housing must pass high-pressure airtightness testing, typically withstanding several times the nominal pressure without bursting or leakage.
