Abstract

Valve with valve body of polymeric material has a flow duct with a constriction serving as valve seating through which a valve core, also of polymeric material, extends. The valve core has a valve head on 1 side of the constriction, and a seating for a spring, on the other. A spring arrangement forces the valve head sealingly against the valve seating. The polymeric material, in both cases, is suitably polypropylene.
