Abstract: Exemplary embodiments are directed to valves, generally including a body assembly and handle assembly. The body assembly generally includes a body and a stem passing through the body. The handle assembly generally includes a handle body and an insert. The insert provides an interface between the stem and the handle body. The insert includes protrusions extending therefrom configured to distribute stress resulting from a moment load applied to the handle assembly through the handle body to reduce failure of the handle body. Methods of positioning a valve are also provided.

Abstract: Exemplary embodiments are directed to butterfly valves, generally including a body assembly and handle assembly. The body assembly generally includes a body, a disc rotationally disposed inside an opening of the body, a cog, and a stem passing through the disc and the body. The handle assembly generally includes a handle body and a force ring. The stem can be rotationally interlocked relative to the disc and the handle assembly. The cog and the force ring can engage to rotationally secure the disc relative to the body. The handle assembly can include a lever and a grip, the force ring, the lever and the grip being pivotally secured relative to each other. The body can include a male radial protrusion and the body assembly can include a liner with a female radial groove. Methods of assembling and positioning a butterfly valve are also provided.

Abstract: Provided is a wafer check valve assembly comprising a body having a mating side including first, second and third surfaces and a shaft groove, a tapered surface of the mating side extends from the third surface toward an inlet side of the body and from a first end to a second end of a port opening; a retainer having a mating side including fourth, fifth and sixth surfaces; and a disc with a shaft; wherein, when the body, retainer and disc are mated together: the shaft is housed between the body and the retainer and within the shaft groove, the first and fourth surfaces are proximal, the second and fifth surfaces are proximal, and the third and sixth surfaces proximal, so to define a pocket housing a gasketing material to form a seal between the body and retainer and to secure together the body, retainer, and disc.

Abstract: Improved flow control assemblies for fluid systems (e.g., industrial and/or commercial systems) are provided. More particularly, the present disclosure provides for advantageous wafer check valve assemblies for fluid systems (e.g., piping systems or the like). The present disclosure provides for advantageous wafer check valve assemblies that include an angled sealing surface, which allows the disc member to seal even with the valve assembly in the horizontal position, and/or to seal without the aid of a spring. Improved, convenient, low-cost and/or effective systems and methods for utilizing improved wafer check valve assemblies in fluid systems (e.g., piping systems or the like) are provided.

Abstract: A system, in certain embodiments, includes a ball valve including a body and a ball disposed within the body. The ball valve also includes a stem disposed within an opening in the ball. The stem is removable by passage through the opening into a bore of the ball.

Abstract: A visual signal of pressure between valve stem seals is given by a rising ring, which moves upwardly with the upper stem seal when there is pressure between the stem seals. The rising ring is held to the stem or valve body around the stem by a retaining ring. The rising ring, in its up position, precludes removal of the retaining ring.
