Application examples:
An equal air pressure is required at working lines (2)
and (4).
A lower air pressure (e.g.3bar) than the operating pres
sure present on the valve terminal (e.g.8bar) is required.
A or B pressure regulator (identifier PH, PG, PC, PB)
Supply process
The work or operating pressure regulator regulates the
relevant pressure of the air (see
1
in Tab.1/9) when the
pressure medium has flowed through the valve. The exhaust
air is passed through the pressure regulator plate and is
switched to the relevant exhaust duct in the valve (see
2
in Tab.1/9).
Exhaust procedure
During exhausting the air is passed unregulated through the
valve and the pressure regulator plate to the valve terminal
(see
3
in Tab.1/9).

the pressure regulating valve.
