SINGLE-ACTING BRAKING VALVES BLEED-AIR
They are composed of a needle throttling, inside which there is a ball
single-acting valve. They can be used in the assembling in manifolds
and integrated blocks and are also used as cylinder braking valves.
This kind of valve can be used also as air breather. By removing the cap
nut it is possible to unscrew the needle and uncover the coaxial passage
which allows the breather of the underlying chamber.
Recommended filtration: 60 micron or inferior.
Max. working pressure: 300 bar
