Special features
Operation with external pilot air
• For vacuum applications
• For working pressures lower than
3bar
• For significant pressure fluctu-
ations in the power section. Power
section and pneumatic control
section are decoupled
• For heavily lubricated air in the
power section
• For manifolds if the pressure zones
are created via ducts 3 and 5
(not possible with 2x 3/2)
• For manifolds or pressure zones
that are equipped with reversible
2x 3/2-way valves (valves on
request)
Operation with internal pilot air
• For small pressure fluctuations in
the power section
• For using pressure regulator plates
in a vertical stacking construction,
also in reverse operation
• As a low-cost solution
Reverse operation with pressure
supply via ducts 3 and 5
• Pressure zone separation via ducts
3and5
– Example: Duct 3 vacuum, duct 5
ejector pulse
– Example: Duct 3 high pressure
for advancing the piston rod of a
double-acting cylinder. Duct 5
low pressure for retracti ng the
pistonrodwithlowenergy
consumption
• 2x 3/2-way valves used as 5/4-way
valve with controllable overlapping
with the reversible variant
Reverse operation with a pressure
regulator plate, compressed air
supply via duct 1
• Reversible pressure regulator com-
bined with a reversible 2x 3/2-way
valve regulates outputs 2 and 4
– AB regulator for outputs 2 and 4
–Aregulatorforoutput4
–Bregulatorforoutput2
• Reversible pressure regulators are
in the control position immediately
after the power supply is switched
on
– Adjustment possible at all times
– Dynamic response characteristics
– Reduced regulator load because
the supply pressure is main-
tained when the valve is switched
– Venti ng not via the regulator
