OG exemplary drawing
 
1. A valve housing for a fluid valve, the valve housing comprising:
at least one fluid channel through which a fluid can flow;
a receiving space for a valve closing body movable in the valve housing, wherein the receiving space has an opening configured to permit the valve closing body to pass therethrough and into the receiving space of the valve housing, the receiving space having a plurality of side walls; and
at least a first valve seat formed in the receiving space, the first valve seat having:
an annular elevation projecting from a first side wall of the plurality of side walls into the receiving space and forming a planar abutment surface for a sealing diaphragm surrounding the valve closing body, the annular elevation forming an undercut in the receiving space with respect to the first side wall; and
an annular sealing edge projecting axially from the planar abutment surface into the receiving space,
wherein the valve housing is an integral injection-molded part, wherein the at least one valve seat is integrally formed at the valve housing.
