Function
TheType3965SolenoidValveIslandcon-
sists of base modules and connection mod-
ules in a row which are connected to each
other over separate common ducts for the
operating medium and exhaust air.
A row starts with a pneumatic connection
module for common compressed air supply
and exhaust. Solenoid valves, each consist-
ing of a solenoid pilot valve and a poppet
valve, are mounted onto the base modules.
The solenoid pilot valves can be actuated by
an electric signal over a common cable,
multi-pole connector, single connectors or a
bus connection for PROFIBUS-DP.
Pneumatic connection modules
A pneumatic connection module is used for
common compressed air supply and ex-
haust.
With internal pilot supply over port (9), the
pneumatic connection module with a pres-
sure reducer is used. For an external pilot
supply over port (8), the pneumatic connec-
tion module without pressure reducer is used.
Solenoid pilot valves
The solenoid pilot valves consist of an elec-
tropneumatic binary converter (A) with a
manualoverride(B)andLED(C).Thepilot
supply for the electropneumatic binary con-
verter (A) is routed through the pressure re-
ducer(5)andtherestrictor(6).SeeFig.3.
Intheidleposition,theapper(2)isliftedoff
the outlet nozzle (1) by the spring (3). As a
result, a pressure lower than the deactivation
pressure of the poppet valve (D) builds up in
the pressure divider, which consists of the re-
strictor (6) and outlet nozzle (1). When the
solenoid coil (4) is energized by an electric
binary signal, the outlet nozzle (1) is closed
bytheapper(2)againsttheforceofthe
spring (3). This causes the pressure in the
pressure divider to rise above the activation
pressure of the poppet valve (D), switching it
to the operating position. After the solenoid
coil is de-energized, the poppet valve (D) is
switched to the idle position again by a re-
turn spring.
Poppet valves
The 2/2-way and 3/2-way poppet valves
consist of a diaphragm switching element
with return spring. The 5/2-way poppet
valve consists of two parallel controlled dia-
phragm switching elements with return
spring. A combination of a maximum of 16
switching functions is possible.
