ABSTRACT:
A valve device has a multi-part housing containing a servo-valve with a stem which is axially displaced to operate the valve and an electromagnet with a rod-like armature which is axially displaced when the electromagnet is energized. A pivotable lever translates the axial movement of the armature to the stem. For adjustment purpose, an adjustment member is in screw-threaded engagement with the lever remote from the stem. The armature is locked for rotation with the adjustment member. A regulator at the opposite end of the armature to the lever and accessible from the exterior serves to enable the armature to be partially rotated for effecting the adjustment.
