Type 407 is a normally-closed
servo-assisted on-off solenoid
valve with a coupled armature /
servo piston (circuit function A).
When de-energized, the spring acts
on the armature to close the pilot
channel in the piston.
2/2-Way, G 1/2 - G 2, Flange connection
When energized, the armature lifts to
open the pilot channel to relieve the
pressure. Even if there is no pressure
differential, the armature lifts the
coupled piston to open the valve.

Zero differential pressure
Body material: brass, grey
cast iron
Fluid temperature
up to180 °C
High reliability
Erosion resistant
