Check valves

Check valve V2OOO

The LOGICA Check Valve V2OOO has been developed for applications in infusion and transfusion technology and also for the use in enteral and parenteral feeding therapy.

The membrane valve is closed in stand-by position. If an infusion line is locked/blocked, the seal mechanism prevents a retro­grade flow into the gravity infusion, even at the lowest flow rates (0.1 ml/h). The safe function of the valve is guaranteed, inde­pen­dently of its position. The check valves can be filled without drawing bubbles. The LOGICA Check Valve V2000 is available with various connector configurations customised to your requirements. All valves with a male Luer lock are also available with a protective cap.

Check valve V2OOO Sealing Element

LOGICA Check valve V2OOO Sealing Element has an integrated elastomeric element at the Luer taper and is compatible according to ISO 80369-7 at the same time.

The elastic sealing element fits to a female Luer counterpart according to ISO 80369-7, and achieves an improved sealing of the connection with even low effort. The low mating force significantly reduces the risk of stress cracks at female Luer connecting pieces. The flexible material avoids an adherence respectively a jamming of the mating surfaces and thereby eases the disconnection of the Luer junction.
