Abstract
A valve includes a housing that surrounds a fluid outlet, a valve element with a longitudinal axis, a valve seat body that surrounds a fluid inlet and which has a sealing seat such that the valve is closed when the valve element bears against the sealing seat and which is coupled to the housing. The valve element is movable relative to the valve seat body in a direction of the longitudinal axis to enable a fluid flow from the fluid inlet to the fluid outlet, the valve seat body surrounds a guide surface to which the valve element is coupled in order to guide the movement of the valve element, and the valve seat body is formed from a harder material than the housing.
