Standard executions
- SFV-10 mb: valve (sealing disk) opens when pressure exceeds 0.010 bar (set at 10 mb).

General information
Features and applications
SFV. valve breather caps are particularly suitable for all those applications (speed reducers, variators or compressors) when the internal air pressure must not exceed a certain value (10 or 100 mb).
In these cases, the safety valve of the cap allows the expulsion of the exceeding air in the reservoir, thus re-establishing the pressure values for which the valve is set.
Sealing disc (closed in normal pressure conditions) prevents dust from getting in and oil-losses.
