Respiratory Valves

These One-Way Respiratory Valves, sometimes referred to as check valves, are for uni-directional respiratory circuits. They permit the flow of gases in only one direction.

• Function in any position; not gravity dependent
• Long life, non-sticky diaphragm maintains elasticity and sensitivity
• Wide range of port sizes 

These valves are available in either a T- or Y-shaped configuration and allow the separation of expired air either for collection or for use with pneumotachometers.

• Inhalation and exhalation ports use a Spiral-Type™ diaphragm to direct flow, which is a patented uni-directional diaphragm
• Function in any position
• Not gravity dependent
• Very sensitive to low flows
• Spiral-Type™ diaphragm has a patented long life, is non-sticking and maintains excellent elasticity and sensitivity
• Easily customized
