A valve including: a flow channel and a closure member. A first sealing surface is provided along walls of the flow channel and a second sealing surface is provided along outer edges of a sealing section of the closure member. A rotation axis is offset from the sealing section by a first predetermined distance and from a centerline of the closure member by a second predetermined distance. To ensure smooth operation of the closure member at least one of the first and second sealing surfaces has a non-conical shape that is at least in one area asymmetric with respect to the center axis of the closure member.

Valve with a sealing surface that minimizes wear

A valve sealing arrangement, including a valve body, and a closing member including a closing member contact surface, and a seat, having a center axis, and provided with a sealing portion with a first sealing surface for making contact with the closing member and a back sealing portion with a second sealing surface for making contact with a surface of the valve body. The seat also includes a bellows between the first sealing surface and the second sealing surface wherein the bellows including bellow members wherein adjacent bellow walls form either inwardly open fold or outwardly open fold and wherein one or more of the bellow members extends in a direction that is oblique to the center axis of the seat.
