A metal gasket, with a section comprising a heel (16) to ensure static sealing and a curved part (15) to ensure dynamic sealing, wherein the curved part (15) exhibits a variation in its radius of curvature while retaining the same direction of curvature.

Metal gasket

An actuator having a tubular body with a cylindrical bore therein within which a piston reciprocates, an output shaft extending into said bore and a linkage for converting the linear movement of the piston into the rotary motion of said shaft. The linkage is contained entirely within said bore. In one form the piston is spring loaded and a spring follower also provides a piston for compressing the spring to permit the force exerted on the piston to be transmitted to the output shaft substantially in its entirety.

The valve of the present invention comprises a tubular body (1) the central ortion (6) of which defines a shutoff chamber (7) which is accessible via an inspection trap (15). Within this chamber (7) there is housed a removable annular pre-body (8) provided with two radial boreholes (9, 10) serving for the rotary mounting of the shaft (11) of the butterfly (12). Sealing means which cooperate with the body (1), the pre-body (8) and the butterfly (12) make it possible to assure the upstream/downstream tightness of the valve. The inspection trap (15) is closed by a cap (28) provided with a passage within which there is rotatably mounted a drive shaft (35) which is coupled to the shaft (11). This structure permits greater ease of access to the inner parts of the valve, a decrease in volume and weight, and greater ease in manufacture.

Butterfly valve of inspectable type

A sealing device for providing the upstream/downstream sealing of a valve comprising a valving member movable inside the bore of a tubular body and comprising at its periphery a sealing surface coming to bear on a sealing packing mounted in the body at the end of the valving stroke. This sealing packing comprises a dynamic annular sealing element and a coronal metal membrane, whose outer edge portion has flat radial part applied axially against a steep side of a shoulder in the bore of the body, for providing static sealing therewith.
