20mm Bag-On-Valve for OTC Medical Applications with Superior Sterility
The 20mm Bag-on-Valve (BOV) is an advanced aerosol dispensing technology featuring a multi-layer laminated pouch permanently fixed to a valve system within a canister. The product formula remains isolated in this sterile pouch while inert propellant (compressed air or nitrogen) fills the space between pouch and canister. Actuation compresses the pouch via propellant pressure, delivering pure product through the valve valve without propellant contact. The male thread design provides secure connection to female canister receptacles.
