    Abstract: The present invention relates to sealing valves used in the petroleum and gas extraction industry, in particular but not exclusively, to medium- or high-pressure ball valves. In particular, the present invention relates to a sealing assembly (101, 102) for ball valves (1), and to a ball valve comprising such an improved sealing assembly. The sealing assembly ensures excellent sealing performance at low and high pressures by exclusively using a thermoplastic material sealing element (31), thus completely eliminating the drawbacks which afflict the sealing system of known type, in particular in relation to the reliability of the sealing elements made of elastomeric material.

    Abstract: A ball valve for a fluid transporting pipe line comprising one or more gaskets (5), where each gasket is mounted in a groove, track or similar area between a first and a second essentially parallel surfaces (7, 8), where each gasket is intended for being pressed against at least a third surface (10) in the groove by means of a force acting against the gasket, where the force is at least applied by fluid in the valve. The force F is divided between two sealing points. The result is an increased sealing force, R FP , or reaction acting between the gasket and the surface of the groove in each sealing point, which increases the sealing efficiency when applying the same force F to the gasket.

    Abstract: The invention relates to the provision of a valve which can be fitted to a pipeline to allow the control of the flow of fluid therealong. The valve includes at least one ball (10) having a first sealing means (14) positioned upstream of the ball and a second sealing means (16) positioned downstream of the ball. The first sealing means is movable under the influence of fluid pressure towards the ball to form a seal thereon and the ball and said first sealing means are movable under the influence of the fluid towards the second sealing means to form a second seal on the ball thus providing a double sealing arrangement with a single ball rather than the conventional two ball arrangements sealing arrangements.
