This piece is called a “stabilizer” it removes the need of a mounting/valve cup. The stabilizer serves as the upper-valve housing, the rest of the valve is mounted accordingly as usual, so the stabilizer is a part of the valve containing stem, gasket, spring and under valve housing. This part is pushed into the can with a force of 900 newton and 12,5mm. This creates a tight seal against the can. (There is also a version with an O-ring seal for higher pressures.) It also works as normal with open can filling. It also has filling benefits and removes the need of the complex crimping station on the filling plant.
Instead of the expensive aluminium or tinplate disc, now a stabilizer made of PA 6.6 is used. The construction of the inner parts such as the stem, steam seal, and spring is identical to standard valves.
Aluminium & PET Aerosol Cans
The specially-designed aluminium cans are tailor-made and look slightly different to traditional aerosol cans, but the machinery needed to produce them is the same. The only difference is a different necking process. Any can manufacturer can produce these cans. Same necking is also applicable to PET Aerosol cans.
