A ball for use within a ball valve includes an outer wall, an inner wall that defines a central bore, and a lattice structure positioned within an interior space defined between the outer wall and the inner wall. The ball may include one or more flow conditioners positioned within the central bore. The ball may be formed via an additive manufacturing process.

A tap (1) is disclosed for delivering liquids, particularly for delivering high- and medium-density liquids from rigid vessels, comprising: a body (3); stem means (9); and elastic actuating means (11) of the stem means (9); air inlet/outlet means (13, 25, 28) in the body (3) and inside the vessel; valve means (7) for passing air; non-return valve means (26) placed between the air inlet and outlet means (13, 25, 28) and the vessel interior and adapted to be guided and driven by the pressure difference between outside the tap (1) and inside the vessel; anti-counterfeiting and protecting means (A); supporting means (E); and an integrated glass (D).

A coupled valve assembly comprises two valves disposed within separate housings and connected with a common coupling, such that a single actuator causes rotation of the valve stems within both valves. The two valves are configured 90 degrees out of phase with each other, such that the actuator will cause one valve to open at the same time it causes the other valve to close. The coupled valve assembly may be used to selectively divert the flow of production fluids from a wellbore to either a production header or a test header within a production manifold.
