Exhalation Valve
Exhalation Valve, also known as Expiratory Valve, Umbrella Valve and Membrane Valve, is a kind of One-way Valve, Check Valve and Non-return Valve that are widely used as sealing parts in respiratory devices like manual resuscitators, ventilators, masks. Exhalation Valve controls the direction of exhaled airflow, ensuring efficient expulsion of the patient's exhaled gas while preventing outside air or contaminants from entering.
Facilitates Exhalation: Allows the patient's exhaled gas to exit the system smoothly, reducing breathing resistance.
Prevents Rebreathing: Avoids the re-inhalation of exhaled CO₂, improving ventilation efficiency.
Maintains Positive Pressure (where applicable): In certain ventilators or CPAP devices, the exhalation valve can regulate pressure to keep airways open.
Reduces Contamination (e.g., in masks): In industrial or medical masks, the exhalation valve minimizes moisture buildup, enhancing comfort.
Device Type | Role of the Exhalation Valve |
|---|---|
Manual Resuscitator (BVM) | Allows exhaled gas to escape, preventing CO₂ rebreathing and improving manual ventilation efficiency. |
| Mechanical Ventilator | Regulates expiratory airflow, controls PEEP (Positive End-Expiratory Pressure), and prevents alveolar collapse. |
Medical/Industrial Masks | Reduces exhalation resistance and minimizes humidity buildup (though valved masks are not suitable for infection control as they may release viruses). |
CPAP/BiPAP Machines | Balances inspiratory and expiratory pressure to improve ventilation in sleep apnea patients. |
Exhalation Valves Produced by Our Factory
Our exhalation valves are available in various elastomeric material including medical and food grade silicone to handle a broad range of media and temperatures. Exhalation Valves can be made by rubber compression molding and LSR injection Molding
Exhalation Valves Material Specification
For Exhalation Valve applied in medical field, the chosen material should reach the FDA Medical Grade and good Biocompatibility. Silicone material VMQ are usually used in medical umbrella valves like Silicone Exhalation Valve and Duckbill Valve in Ventilator, Manual Resuscitator. With its good biocompatibilty and high tensile elastic, VMQ material are generally resistant to Moderate or Oxidizing Chemicals, Concentrated Ozone, and Sodium Hydroxide, thus achieving the effect of sterilization.
According to your needs, Our company Xiamen Better Silicone can also provide above mentioned materials to make and customize high quality Umbrella Check Valves and Exhalation Valves in various field of use by Compression Molding or Liquid Injection Molding.
