This video shows the sealing ability of my MBC when pressure (boost) and vacuum is applied.
Valve in video is adjusted to open at just over 10psi, you can see that it holds 10psi of pressure.
When vacuum is applied, again it seals perfectly.
Inside is not only a ball and spring, but also features a sealing diaphragm.
Very nice ! The sealing ability is important on MBC and in direct relation with the quality of building.
