Medical IV Inline Check Valve (Anti-Backflow/Anti-Siphon)
Key Features:
- One-way flow: prevents backflow and cross-flow, reduces air ingress risk
- Low cracking pressure: suitable for gravity infusions; typical 3–10 kPa (customizable)
- Transparent housing: visual check for liquid and bubbles
- Compatibility: Luer-lock/slip or barbed ends (fits tubing OD 3.0–4.5 mm)
- Safety marking: flow-direction arrow to avoid misassembly; anti-siphon option (AS)
Applications:
- Backflow prevention in gravity infusions
- Cross-flow prevention in multi-line setups
- Protection during aspiration/bolus to avoid air ingress
- Line safety during transport or bag changeover
Compliance & Materials:
- Standard: ISO 80369-7 (Luer); designed per ISO 8536-4 when integrated in infusion sets
- Sterilization: EO (ISO 11135); non-sterile bulk available for integration
- Materials: PC/PP housing; silicone valve disc/membrane; latex-free and DEHP-free options
Performance Notes:
- Flow/pressure-drop curves available per specified viscosity and temperature
- Install per flow-direction arrow; point arrow toward patient or designated flow direction
