pMDI Valves
Bespak® pMDI valve and actuator
Valves for low carbon pMDIs
With our leading position in the global pMDI industry, we take our responsibility to lead the green transition seriously. Bespak valves have been optimised during a five year research and development programme, and are ready for testing with formulations incorporating both of the new sustainable propellant candidates. As a result of extensive elastomer studies, physical stability testing and aerosol performance modelling, we are also able to help guide the selection of critical components using our proprietary Bespak® Valve/Actuator Selector Tool.

Easifill valve for patient convenience
The Bespak BK361 Easifill pMDI Valve is specially designed to optimise patient adherence by removing the need for initial priming and re-priming before each use. The engineered ‘fast fill and drain’ design ensures complete filling of the metering chamber after actuation or storage to eliminate loss of prime, while the easy-to-use patient-centric design enhances dosing convenience.
BK361 – designed for adherence
Fast fill and drain
No priming required – simply invert and shake
Sleek economic design, ideal for suspensions with high deposition - minimises loss of dose due to drug adhesion in the chamber
Improved chamber agitation compared to capillary retention valves
Ideal for use with breath-actuated devices as well as standard press-and-breathe
