Material

Polyamide based (PA) technopolymer:

Cover: RAL 2004 orange, semi-matte finish, with graphic symbol 'valve'.

Threaded fitting with splash guard: black, semi-matte finish.

Packing ring

NBR synthetic rubber flat washer.

Overpressure valve

Technopolymer with NBR synthetic rubber O-ring.

Stainless steel spring, set at around 0.350 bar or 0.700 bar.

Maximum continuous working temperature

100° C.

Standard executions

SFV-AP-350MB: valve opens when pressure exceeds 0.35 bar (set at 350 mb).

SFV-AP-700MB: valve opens when pressure exceeds 0.700 bar (set at 700 mb).

Features and applications

SFV-AP 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 (350 or 700 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.

Valve (closed in normal pressure conditions) prevents dust from getting in and oil-losses.

SFV-AP breather caps are made with a special internal geometry which stops the leakage of the fluid to the outside, even in the most critical cases of strong fluid projections.

Technical data

Air flow rate for the different executions of breather caps can be obtained from the diagram on the basis of the difference of air pressure inside and outside the reservoir.
