11 ABSTRACT OF THE DISCLOSURE A valve with a valve body (11, 43) in the form of a ball or of a segment of a ball has a second, concave, spherical sealing surface (20, 53) which is provided to be resiliently urged against a first sealing surface of the valve body, and at least an outer, cylindrical surface (21, 65, 66) which slidingly contacts a cylindrical guiding surface (22, 55, 56) of equal diameter in the central part of the valve housing. A spring washer (17, 82) abuts an end surface (24, 73) of the seat ring and is firmly clamped with its peripheral portion between an end surface (27, 81) of the central part of the valve housing and an end surface (28, 62) of an end fitting. The end surface of the seat ring comprises an annular abutment surface (24, 73) at a radial distance from an interior of the peripheral portion of the spring washer. The abutment surface is projected in the axial direc- tion toward the end fitting relative to a first, annular portion (23, 70) of said end surface of the seat ring.
