Two-Way Non-Rebreathing Respiratory Valves

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

These valves are available in a variety of sizes for small animals to large dogs. Select a valve according to the animal size used and the resistance to flow.

Two types of connectors are available: straight and standard medical tapers. Connectors having an OD or ID of 7.5, 10.5, 15 or 22 mm are standard medical tapers. All the other sizes are straight connectors. Both types allow quick, leak-free, twist attachment of the valves to other components.
