摘要： A component with sealing grooves for receiving facial seals and with protective arrangements to protect such seals is provided. In one embodiment, the component is a ball valve including a flow control assembly with two closure members having outer surfaces with sealing grooves and protective ridges. The protective ridges facilitate separation of the two closure members from two connectors of a fluid conduit during installation of the body between the two connectors. Additional systems, devices, and methods are also disclosed.

摘要： The invention relates to a valve assembly which includes at least one, but typically two, balls located along a passage and which balls can be moved between open and closed positions to selectively control the passage of fluid along the passage. The valve assembly includes at at least one end thereof a retaining assembly which allows the effective sealing against one surface of a ball and retention of the same in position. A sealing assembly is also provided when two balls are provided, intermediate the same, which allows effective sealing to be achieved and at least one of the two trunnions which allows each of the balls to be mounted within the valve body is located only internally of the valve body. The components of the valve assembly which are located within the same can in one embodiment all be inserted into and located within the valve body from one common end.

摘要： A high differential pressure, low torque precision temperature control valve is disclosed herein. This valve is trunnionated with stem components that are separable from the plug for ease of maintenance and manufacturability and thus reducing the need to remove the entire plug and sealing assemblies in the field. Field repair of stem sealing devices can be accomplished inline . The stem design can be smaller in diameter with smaller bearing surfaces than would be anticipated creating a lower requirement of torque to rotationally transposition the plug within the fluid chamber while under high pressure. This valve's lower trunnionated stem is stationery reducing the problems associated with o-ring failure and leakage problems with objects that rotate. Due to the design of the orifices in the plug, this valve is capable of repeatability at lower opening ranges than prior art valves and reduces jetting, caviation and erosion often associated with lower opening ranges. Sealing devices are tensioned onto the plug through the use of non-metallic o-rings reducing wear and friction issues thereby further reducing the torque requirement to adjust the valve. The throughports of the plug in this valve are designed such as to create an equal percentage characteristic that does not exceed prescribed linear flow characteristics and provides a relatively constant total combined Cv over the travel range of the plug.

摘要： The present invention relates to a cock having a spherical plug which is supported between two annular sealing elements intended to seal the inlet channel and outlet channel thereof, of which two sealing members at least one consists of a resilient sealing member engaging said plug of said cock in an axially prestressed condition and of a coaxially located support member which limits the axial movement of said plug due to an operating pressure, which axial movement causes a deformation of the sealing member. In order to have an excellent sealing of the cock at unlimited temperature and simultaneously small operating moments the annular sealing element is shaped as a thin-walled sheet metal body which at one end is rigidly mounted to the casing of the cock and which sheet metal body comprises two coaxially arranged ring shaped sections, of which the one is shaped and arranged as deformable sealing member and the other is shaped and arranged as rigid support member mounted to said casing.

摘要： An improved ball valve wherein each annular valve seat comprises a stamped metal seat ring disposed in a respective end of the valve body with the inner periphery of the seat ring conforming to and sealingly engaging the valve ball. An elastomeric annular seal is bonded to the side of the seat ring adjacent the valve ball and sealingly engages the valve ball and the bore through the valve body. The outer periphery of the annular seal has a diameter greater than the bore and is deformed by the bore to provide sealing engagement therewith and to retain the annular valve seat in the valve body during shipment and assembly of the valve in a pipeline. An elastomeric annular seal bead is bonded to the side of the seat ring opposite the annular seal to provide sealing engagement between the valve and a pipe flange carried by the pipeline. In another form the stamped metal seat ring is sized and shaped to conform to the periphery of a relatively deep counterbore formed in the valve body. In another form a circumferential bead is formed on the outer periphery of the annular seal and matingly engages an annular groove formed in the bore through the valve body.

摘要： A valve assembly, particularly useful between flanges, which utilizes a housing unit and a separate valve unit. The housing unit provides a supporting housing adapted to be supported between the flanges and to include a valve operator and a first valve stem. The valve unit is sized to be inserted in the housing unit and includes the valve member, seats, and at least one additional valve stem. The valve stem carried by the housing unit is insertable lengthwise into connection with the valve stem of the valve unit. In an assembled position, the valve unit is sealed against the flanges and prevents the housing unit from being contacted by fluid controlled by the valve.
