SFW-VP

Applications

SFW-VP pressurised caps are suitable for earthworks and agricultural machinery, and in general for machinery that can be left unattended.

Features

The use of SFW-VP pressurised breather cap which create a pressure plenum chamber right above the oil level within tested limit conditions, in order to avoid any reservoir deformation, offers also other advantages (see example of functioning in the SFW.).

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.

 

Special executions on request

Caps with flat dipstick, flat section phosphatised steel.

'Vandal-proof' safety device functioning

• Cap screwing.

Screw the cap clockwise until the torque limiter clicks. For optimal tightening, it is advisable at this point to continue tightening with the key inserted: turn the cap cover clockwise until you reach one of the two points of resistance. Only in these two positions is it possible to fully insert the key to make the cover integral and to finish tightening.

Once the key has been removed, it is impossible to unscrew the cap, preventing any attempts at tampering (vandal-proof function).

• Cap unscrewing.

Turn the cap clockwise until one of the two resistance points is reached. Only at one of these two positions the key, which couples the cover to the threaded connector, can be competely inserted and the cap can be unscrewed.
