Disadvantages compared with the AB pressure regulator:
It is not possible to use 2x3/2−way valves (identifier
T32
C −A, T32 U −A, T32 H −A) in combination with ducted sole
noid exhaust 82/84, as reversible pressure is present at
valve interface.
Sensible combination with an intermediate throttle plate
is not possible.
Examples of application:
If, instead of the operating pressure of the valve terminal,
two further different pressures are required in channels 2
and 4.
If fast exhausting is required.
If the pressure regulator is always to be set.
Notes on installing this pressure regulator see chapter 3.3.6.
