A valve and a bearing surface for a valve and a manufacturing method of the same including a valve body with a main channel extending between a fluid inlet and a fluid outlet, and a closing member provided in the main channel. The valve further includes a shaft connected to the closing member for moving the closing member between an open and a closed position. Moreover, the valve includes at least one bearing surface between the valve body and the closing member or the valve body and the shaft, the bearing surface further including a plurality of cavities filled with solid lubricant. An advantage of the claimed valve is that the lubricant is maintained longer on the bearing surfaces and thus lubrication periods and valve lifetime are increased.

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.

A valve enclosure and side handle faucet system comprising the valve enclosure. The valve enclosure comprises an inlet portion, an outlet portion and a valve cavity. The valve enclosure further comprises a ball valve and is mounted to the side of a spout such that fluid enters the valve cavity perpendicularly from a fluid inlet line and exits the cavity perpendicularly from an outlet such that the distance between the input and output flow to the cavity is minimized.

A high pressure fluid system including enhanced safety, maintenance and servicing features. The system can include a CAM assembly module, having a valve seat assembly, seal cartridge assembly and inlet manifold, that is easily installed in and removed from a frame and/discharge manifold as a single unit. A discharge manifold can isolate different pressure rated passageways of the system, and multiple rupture discs associated with the same. A discharge manifold end plate can be included to provide ease of repair of discharge outlets and to establish a plumbing system for the rupture discs. A quick coupler can facilitate connection between a plunger of the seal cartridge assembly and a cross head stub connected to a power frame. A lubrication valve assembly can provide and meter lubrication from a high pressure inlet source to a plunger and packing of the seal cartridge assembly.

A pressure regulator includes a cylinder and a piston contained in the cylinder. First and second O-rings are attached to the cylinder and configured to form a seal between the cylinder and an interior wall of the piston. The pressure regulator has a lubrication system that includes a lubrication reservoir between the first and second O-rings defined by an annular groove in an exterior surface of the piston and the interior wall of the cylinder, and an input port extending through the cylinder to the lubrication reservoir. The piston is configured to move along a central axis relative to the cylinder between first and second positions. The first and second O-rings are displaced from the input port during movement of the piston between the first and second positions.

A sealant gun is inserted into a limited space work area to engage a buttonhead fitting supported by a fitting assembly perpendicular to a valve stem extending from a tapered plug valve. The fitting assembly orients the buttonhead fitting on the valve stem for movement of the sealant gun in a single vertical direction to engage the buttonhead fitting. The sealant gun injects a sealant under pressure through the buttonhead fitting and the valve stem into a tapered bore of the valve body. The tapered bore receives a tapered plug on the end of the valve stem for movement into and out of a closed valve position with the tapered bore. The sealant is injected between the tapered plug and the tapered bore to provide a seal therebetween that prevents the escape of the fluid flowing through the valve from the valve through the valve stem to the atmosphere.

A high pressure valve having a valve body with a cylindrical bore and a movable member for selectively moving between an opened valve position for opening the cylindrical bore and a valve closed position for closing the cylindrical bore. An outer surface of the movable member exposed to the cylindrical bore in the valve closed position has a recess defined therein.

An actuator converts linear motion into rotational motion. The actuator includes a power piston having a longitudinal axis. The power piston is configured to move back and forth along the longitudinal axis. A slider bearing is disposed within a cross-bore opening in the power piston. The cross-bore opening has a slider bearing axis orthogonal to the longitudinal axis. The slider bearing is configured to move back and forth within the cross-bore opening. An output shaft has a central axis orthogonal to both the longitudinal and the slider bearing axes. The output shaft includes an eccentric shaft pin inserted through a slot in the power piston and disposed within a cavity of the slider bearing. The eccentric shaft pin is offset from the central axis of the output shaft. The reciprocating movement of the power piston causes the slider bearing to move back and forth rotating the output shaft.
