Philips Respironics Pressure Valve

Protect your CPAP or BiPAP unit with this genuine Philips Respironics Pressure Valve—an essential safeguard for machines connected to humidifiers or oxygen therapy. This compact, spring-loaded one-way valve prevents water or oxygen from flowing back into your device when it is turned off, ensuring the integrity and longevity of your machine.

Key Features & Benefits

• Automatic Back-Flow Protection: The valve closes automatically when your therapy unit is powered off, sealing the circuit and preventing moisture or oxygen from entering.

• Seamless Therapy Operation: When your CPAP/BiPAP is running (at pressures of ~2 cm H₂O or greater), the valve opens immediately to allow unrestricted airflow to your mask—without impacting treatment.

• Universal 22 mm Connections: Engineered for broad compatibility, it features standard 22 mm inlet/outlet connectors—fit for most Philips and third-party CPAP/BiPAP circuits.

• Essential for Oxygen Use & Humidification: Especially important when adding supplemental oxygen or using a heated humidifier—both situations where back-flow could damage your machine or create a hazard. 

Important Notes

This valve is not an exhalation port and does not replace the mask vent needed for exhaled air discharge. Always use with a mask that has a built-in exhalation vent.
