Abstract
A plate or check valve, for diaphragm pumps, including a valve chamber in which at least one valve seat is provided that interacts with a valve plate that is elastically pretensioned via outer edge mountings such that a closing body of the valve plate can be moved from a closed position, in which it sealingly lies on the valve seat, into an open position against the elasticity of the valve plate. The outer edge mountings have webs and connecting brackets which are connected to the web ends facing away from the closing body. The outer edge mountings are disconnected from one another and only engage on the closing body, each of the outer edge mountings has at least two webs that are connected together via a connecting bracket, and each connecting bracket engages behind at least one paired holding base of the valve housing.
