Pressure regulator A or B
(identifier PH, PG, PC, PB) Mode of operation:
Pressurizing
The pressure regulator A or B regulates the relevant
pressure of the work air (see
1
in Tab.1/12) when the
pressure medium has flowed through the valve. The exhaust
air is passed through the intermediate plate and is switched
to the relevant exhaust channel in the valve (see
2
in
Tab.1/12).
Exhausting
During exhausting the air is passed unregulated through the
valve and the pressure regulator (see
3
in Tab.1/12).
