Abstract
A solenoid valve includes a manually operable override with a latch handle that comprises a profile for, in a latched position, latching a valve core by having the profile block an operator part of the valve core in a longitudinal direction, and that is biased towards its latched position, preferably by means of gravitational forces acting upon it. The profile includes a recessed hook portion for, in an unlatched position, abutting sideways against the operator part for limiting the latch handle to move towards its latched position. A release handle is movably connected to the latch handle from a starting towards a release position for forcing the operator part to slide along the hook portion in the longitudinal direction until it no longer abuts sideways against the operator part and releases the biased latch handle.
