    Abstract: A ball valve for use in a hydraulic supply system is described. The ball valve includes a valve body defining a fluid passage including an inlet and an outlet, a ball having an opening therethough and having an open position and a closed position within the fluid passage and a normal operating range between the open position and the closed position, a manual valve operation mechanism, an input shaft connected to the manual valve operation mechanism, and a gearing assembly including an output shaft, the gearing assembly connected to the input shaft and the output shaft connected to the ball. Rotation of the manual valve operation mechanism causes rotation of the ball along a full operating range within the valve body and the gearing assembly includes a feedback mechanism that is actuated after the ball has rotated outside of the normal operating range.

    Abstract: A sealing arrangement for a valve can include a first seat portion, a second seat portion extending from the first seat portion in a first direction, and an anchor portion extending from the first seat portion in a second direction transverse to the first direction. The anchor portion can include an anchor section having a first sealing surface to provide a first seal within the valve and a convolution section arranged between the first seat portion and the anchor section and including at least one bend that is resiliently compressible in the second direction so that the first seat portion moves in the second direction when the convolution section of the anchor portion is compressed in the second direction.

    Abstract: A ball valve system includes a body having an upstream end and a downstream end and a ball within the body between the upstream end and the downstream end, the ball being rotatable about a vertical axis to move between a closed position and an open position. The ball valve assembly includes a stem movable in an actuation direction substantially parallel to the vertical axis, the stem including a recess at a proximal portion of the stem, a guiding member extending within the recess of the stem, the guiding member being configured to prevent rotation of the stem or cause rotation of the stem, and a lubrication port in fluid communication with the recess.

    Abstract: Disclosed embodiments include ball valves with an asymmetric seal and seat, to minimize seal wear. In embodiments, a seal is disposed upon a ball with a first and second section, where the first section of the seal is disposed at a different angle from the second section. A seat has a first and second section at different angles that correspond to angles of the first and second section of the seal, respectively, such that the seal fully contacts the seat when the ball is in a closed position. When the ball is rotated to an open position, the different angles of the first and second sections allow the second section of the seal to clear the first section of the seat without contact.

    Abstract: A valve (10) of an embodiment of the present invention has a tapered section (55) on an opening side of a depression (51a) of a body (1). When a projection (4b) of a ball (4) is inserted into the depression (51a), a part of a tip end edge of the projection (4b) is brought into contact with the tapered section (55), and the tapered section (55) guides the projection (4b) so that the entire circumference of the tip end edge of the projection (4b) is located on a bottom side with respect to the tapered section (55).

    Abstract: A control valve assembly includes a valve body defining an inlet, an outlet and a fluid flow pathway therebetween. A ball valve is positioned within the fluid flow pathway and includes a rotatable ball having an inlet opening, an outlet opening and a flow pathway therebetween, an upstream seat ring positioned at an inlet side of the ball, and a downstream seat ring positioned at a downstream side of the ball, the seat rings being configured to substantially seal off fluid flow between upstream and downstream sides of the ball except through the ball fluid flow pathway. At least one of the upstream and downstream seat rings is a dynamic sealing seat ring. A retainer ring is positioned between the dynamic sealing seat ring and a portion of the rotatable ball to substantially prevent deformation of a portion of the dynamic sealing seat ring in a direction toward the ball.
