ABSTRACT:
The present invention relates to a valve device for regulating a fluid, particularly a gaseous fluid, in a conduit portion, comprising a valve body fixed to a support spindle extending transversely into said portion and mounted with the ability to rotate therein, said conduit portion comprising, on either side of said spindle, opposing internal steps forming two bearing surface portions for corresponding edge parts of said valve body, in the closure position thereof, each step extending substantially over approximately half of the internal circumference of the conduit portion in the region of the mounting position of the support spindle.Device characterised in that the opposing edge parts of the plate-shaped valve body comprise deformable sealing means for operation thereof in the closure position of said valve body, in the form of two flexible lips extending from said edge parts asymmetrically on either side of said valve body and at an inclination to the plane of the valve body, a first toward the exterior and the second toward the interior.
