2x 2/2-way valve
• 1x normally closed
• 1x normally closed, reversible
• Pneumatic spring return
• Operating pressure > 3bar
• Vacuum at port 3/5 only
1) If neither solenoid coil is energised, the valve moves to its mid-position by means of spring force.
If both coils are energised at the same time, the valve remains in the previously assumed switching position.
-H- Note
A filter must be placed upstream of valves in vacuum mode. This
prevents the ingress of foreign matter in the intake air into the valve
(e.g. when operating a suction cup).
