ation
Solenoid valves actuated on one side
The solenoid valves consist of an electro-
pneumatic binary converter with (option-
al) manual override and a booster valve
actuated on one side with return spring
(Fig. 1).
The pilot supply for the electropneumatic bi-
nary converter is routed internally through
the booster valve (delivered state). The so-
lenoid valve can be converted to accept an
external pilot supply at port 9 by turning a
gasket.
The pressure reducer

reduces the pilot
supply pressure to 1.4 bar.
In the idle position, the flapper
 is lifted off
the outlet nozzle by the spring  . As a re-
sult, a pressure lower than the deactivation
pressure of the booster valve builds up in
the pressure divider, which consists of the re-
strictor

and outlet nozzle  .
