Universal Inline Pressure Valve for Preventing Backflow in CPAP/BiPAP Systems OPT944E Nova Micro's soft silicone pillowsThis Pressure Valve is a spring loaded valve that helps prevent the back flow of oxygen (O2) or water from the patient circuit into CPAP BiPAP systems when the machine is turned off. Any back flow passes out of the circuit through vents in the valve. When the CPAP BiPAP machine is operating, the valve allows air to flow normally through the patient circuit but when the pressure is eliminated the valve seals to prevent backflow.
