Prestosil - Silencer and fow con-
trol valve
Principle
Prestosil silencers are designed for mounting
into the exhaust valve of single acting
cylinders or on the directional control valve.
Operation
Noise reduction
The escaping air is pre-expanded in the
chamber of the silencer. It then fows through
a sintered bronze cartridge whose design
provides a complete expansion of the
exhaust air.
Flow control
The adjusting screw of the uni- direction fow
control valve allows fne adjustment of the
restriction and thus precise control of the
piston-rod speed. The setting is secured by
a lock nut.
