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