Design and principle of operation
3 Design and principle of oper-
ation
The Type 3930 Solenoid Valve is suitable for
controlling pneumatic rotary actuators with
NAMUR interface according to VDI/
VDE 3845.
The principle of operation is based on a so-
lenoid plunger system with a downstream
spool-type poppet valve. When the solenoid
coil is energized, the solenoid plunger is lift-
ed and opens the connection for the pilot
control of the poppet valve. The pressure
supplied over port 1 causes the switching of
the poppet valve.
The Type 3930 Solenoid Valve implements
3/2-way or 5/2-way functions with K
VS
0.85 (see Fig. 1 ) depending on the version.
