Abstract

A seat valve with electromagnetic actuation having switching noises during closure of the seat valve should be noticeably reduced independently of a temperature of a fluid in the seat valve, without considerably increasing the production costs of the seat valve. A sealing body of the seat valve is produced from a plastic which is selected from the group (PEEK, PEI, PASU and LCP), and the flow of force for fastening and for transmitting structure-borne sound from a sealing seat to a fastening surface has at least one transition from a metallic component to a component composed of plastic and a transition from the component composed of plastic to a fastening surface of some other metallic component. The seat valve may be used in hydraulic brake systems of vehicles, but also in gear mechanisms or hydraulic systems.
