Beschreibung
Zusammenfassung:	Disclosed herein is a differential pressure poppet valve comprising: a valve body (111), the valve body having a flow inlet (118) and a flow outlet (120); a shutter guide (116) disposed inside the valve body (111); a poppet shutter (112) guided by the shutter guide (116); a flow passage (126) from the flow inlet (118) to the flow outlet (120), said flow passage being formed between an inside surface of the valve body (111) and an outside surface of said shutter guide (116) and of said poppet shutter (112). The valve further comprises at least one biasing member (114) configured to bias the poppet shutter (112) towards a closed position so as to block the flow passage through the flow inlet (118). To reduce impact wear at least a first damper (148) is provided, configured and arranged to at least partly absorb impact energy of the poppet shutter (112) when said poppet shutter open or closes the flow inlet (118).
