General information
Features and applications
Push-fit avoids the need to screw/unscrew, allowing for quick installation. See Fig.1 for the dimensions of the assembly hole. Chamfer hole 1x45° the outside survace to make assembly easier.
TP-SV+a 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.
The product is designed to vent slight overpressures; the pressure inside the tank must not exceed 200 mb, under optimum conditions of cleanliness of the assembly hole and at room temperature.
Technical data
Air flow rate for each model can be determined from the graph calculating the difference between the pressure inside and outside the reservoir.
