Abstract: A ball valve having improved sealing between the valve member and the valve body is presented. Improved sealing is realized by providing a sealing member that is allowed to float on the outer surface of the valve member in the closed position. By being able to float on the outer surface, the sealing member can compensate for any variations in the valve member as a result of machining tolerances or variations in position of the valve member due to changes in pressure within the valve, thereby providing dynamic sealing The dynamic sealing is also provided by configuring the valve member such that it causes the sealing member to be exposed to a higher biasing force in the closed position than in the open position.

Abstract: A trunnion type ball valve having valve seats that are laterally moveable within seat recesses of the valve and establish sealing engagement with a valve ball member that is trunnion supported for rotational movement between open and closed positions. The valve seat members are self-centering for optimum sealing engagement with the spherical sealing surface of the ball member. The internal geometry of the seat assemblies are designed to permit optimum flow through the valve mechanism even under circumstances where the seat members are located in laterally off-center relation with respect to the centerline of the flow passages due to self-centering seat movement. The ball valve is readily adapted for fire-safe application via the use of heat resistant seals and metal-to-metal sealing of components to prevent or minimize leakage in the event of seal destruction or degradation by excess heat.

Abstract: A ball valve (10) is disclosed with an orifice (58) to control the flow of fluids in which the downstream seal (52) is never directly exposed to erosive wear from the fluid flow. The orifice (58) is only open in a limited range of the ball (42) rotation. Upon rotation of the ball (42) from the full closed position, the orifice starts to open on the outlet side (62) first and after the outlet orifice is fully open the orifice opens to the inlet side (60). The size of the opening on the inlet side (60) can be adjusted to control the flow rate of fluid through the orifice (58) in the ball (42). When closing the valve, the inlet side closes first and then the outlet side. The orifice (58) of the ball (42) thus passes the outlet seal (52) under no-flow conditions, and gross erosion of the outlet seal can be avoided.

Abstract translation: 公开了一种具有孔口（58）的球阀（10），以控制流体的流动，其中下游密封件（52）不会直接暴露于来自流体流动的腐蚀性磨损。 孔口（58）仅在球（42）旋转的有限范围内打开。 在球（42）从完全关闭位置旋转时，孔口首先在出口侧（62）开始打开，并且在出口孔完全打开之后，孔口通向入口侧（60）。 可以调节入口侧（60）上的开口的尺寸以控制通过球（42）中的孔口（58）的流体的流量。 关闭阀门时，入口侧首先关闭，然后关闭出口侧。 因此，球（42）的孔口（58）在无流动条件下通过出口密封件（52），并且可以避免出口密封件的严重腐蚀。

Abstract: A control valve of the ball type with bi-directional shutoff capabilities is disclosed. The ball valve including an inlet and an outlet, a ball element and a seal assembly. When closing the valve, the ball element, which is eccentrically mounted on a shaft, rotates to abut the seal assembly. While closed, the seal assembly including a seal housing, a main seal and a resilient member, contacts the ball element at the main seal, while the resilient member biases the main seal toward the ball element. The seal assembly further includes a secondary flowpath between the main seal and seal housing, which is restricted by a high temperature seal.
