Abstract

A valve (1) comprising a first housing part (2) and a second housing part (3), the first housing part (2) and the second housing part (3) being made from a sheet metal material, and being joined by means of welding, preferably laser welding, to form a closed housing of the valve (1). An actuator (9) is arranged inside the housing for driving movements of a first valve member (7) and/or a second valve member (8), said actuator (9) being arranged directly in a flow of fluid flowing in the fluid flow path during operation of the valve (1). The valve (1) is hermetically sealed due to the welding of the housing parts (2, 3).
