Valve Adapter Oxygen for filling a valves with residual pressure valve

G 3/4 male on G 3/4 female

Residual pressure valves automatically close the gas space of a compressed gas cylinder when mechanical cylinder drops below a certain cylinder pressure (eg 2-3 bar). In this case, the handwheel does not need to be operated, that means the valve is closed in any case - even if it was forgotten to close it. EP 0 077 828 B1 describes a valve with a pressure-dependent closing device (residual pressure valve) which is spatially and functionally separated from the shut-off valve contained in the valve.)
