seadw mbw hv valve

[ayrtontre]

someone know if the HE valves are operable in the MBW cases.

[freddy333]

Nope, not unless you make them operable.

I bought my MBW SD in 1997 and it has a functioning (and waterproof) HE valve. It all depends on which one you get, new or old. Freddy's right, the new ones are for looks only.
