Abstract

The valve comprises a housing with an upstream inlet, a valve inlet for communicating with a downstream flow, and a valve outlet. A pressure maintaining arrangement comprises a diaphragm and a valve member movable along an axis of the valve, the valve member setting itself in a balance between the upstream pressure on the one hand and the downstream pressure as well as a spring force on the other hand. The valve member comprises a circumferentially extending skirt (9) facing the valve seat (12). The skirt (9) comprises an abutment surface (17) facing an opposing surface (17a). An inner corner formed between said abutment surface (17) and an inner surface (18) of the skirt (9) is chamfered or establishes a non-linear transition (19) between the abutment surface (17) and the inner surface (18), said chamfer or transition (19) extending less than a distance (A) of 0.1 mm from the inner surface (18) in a direction towards the abutment surface (17) and less than a distance (B) of 0.1 mm from the abutment surface (17) in a direction towards the inner surface (18).
