    Abstract: The present invention relates to valve apparatus (1) comprising a valve member (4) moveable for controlling flow through a fluid carrying bore (3). The valve member comprises a valve element (13) coupled to a stem element (5) extending within a stepped stem bore (8) in a stem body, the stem element projecting out from the stem body (2) through a stem bore opening. The valve member is further provided with a pressure-energizable multi-element stem seal (9) within the stem bore, the stem element having a profile which inhibits compete removal of the valve member through the stem bore opening.

    Abstract: A pressure-tight stein cylinder seal and a self-energizing stein shoulder seal matching the stein cylinder seal that both use an equilaterally triangular soft ring as their sealing element, wherein their designing rules are first, by means of wedging function of a hard gland coaxial with the stein cylinder, to convert their original axial tightening force 2f respectively into a radial compression force 4f/√3 of their soft ring 04 on the stein 02 cylinder and another radial compression force 2f of their soft ring 06 on the stein 02 shoulder and ensure that the two soft rings are so compressed from a great room to a small room as to be able to pass a pressure or stress exactly to each different direction, then to cut off their off-stein corners to give their cavities an opening or give each soft ring an axial compressing allowance, and last, by means of anti-extrusion metallic C-rings without axial resistance, to close each opening to provide a full support for the sealing deformation of their soft rings compressed in their cavities.

    Abstract: Example aspects of a method of using a bonnet and stuffing box assembly and a method of manufacturing a bonnet and stuffing box assembly are disclosed. The method of using a bonnet and stuffing box assembly can comprise providing a stuffing box, a bonnet, a bushing assembly, and a stem, the stuffing box and the bonnet defining an assembly bore, the bushing assembly received in the assembly bore, the bushing assembly defining a bushing bore, and the stem received through the bushing bore; sealing the stem relative to the bushing assembly to prohibit fluid flow through the bushing bore; sealing the bushing assembly relative to the bonnet to prohibit fluid flow through the assembly bore; and turning the stem relative to the bushing assembly, bonnet, and stuffing box to actuate a valve.

    Abstract: Described herein is an improved ball valve assembly for use in a tank or a tank-like container. This improved ball valve assembly prevents leakage of a liquid with corrosive and abrasive contaminants within the tank or a tank like container. This improved ball valve assembly is especially useful in a railroad tank car that contains a liquid commodity in whenever a tank is mobile and subjected to wide temperature variations. The improved ball valve assembly contains a ball component made of a ceramic material. A ceramic wiper (i) mechanically seals against the ball component and (ii) prevents contaminants from embedding within, or otherwise abrading, top and bottom seats within the ball valve assembly. Also contained in the preferred embodiment of this invention is an improved drive coupling that (i) eliminates the previously existing need for custom square drive tool (ii) pre-attached to the ball valve assembly. The current invention also includes an improved stem packing assembly that reduces the number of annular components along the stem of the ball valve assembly.

    Abstract: Provided is a ball valve which may be manually opened and closed with ease by reducing handle torque and can securely prevent leakage. The present invention relates to a ball valve, comprising a valve body which has a fluid inlet passage, fluid outlet passage, and a communicating part provided between these passages, a ball which has a fluid communication passage and preferably is arranged on the communicating part of the valve body to be able to rotate about a reference axis, a substantially cylindrical ball seat which preferably has a desired opening part on its peripheral wall and is arranged between said ball and said valve body, a ball seat pressing part arranged inside said valve body so as to be adjacent to said ball seat, and a presser screw arranged to be screwed to fit in the inner periphery of said valve body. The ball valve preferably performs communication and interception between the fluid inlet passage and the fluid outlet passage by the rotation of the ball about the reference axis. The presser screw preferably presses the ball seat pressing part by adjustment of its tightening force and presses the ball seat pressing part without contacting the packing.

    Abstract: A ball valve includes a valve element and a single piece packing that seals the valve element within a valve cavity. The single piece packing is installed over the valve element at room temperature or may be molded thereon. The valve element may include a flow control element such as a ball and upper and lower trunnions. The various dimensions of the valve element and packing are selected to facilitate room temperature assembly and to substantially reduce the volume of packing material, thereby improving the performance of the valve over wider temperature ranges and pressure ratings.
