  • Piston actuated pressure reducing valve
    Patent number: 5632466
    Abstract: A valve includes a housing having an inlet and an outlet for the flow of a first fluid therethrough. A cup-shaped cover dome is attached to the housing. The cover dome has a cylindrical bore. A valve stem has a plug to regulate the flow of the first fluid through the housing. A piston is connected to the valve stem. The piston is reciprocatably received within the cylindrical bore of the cover dome to define a first chamber disposed between the piston and the housing and a second chamber disposed between the piston and the cover dome. The piston has a sliding circumferential surface received in an inner surface of the cylindrical bore.

  • High temperature fluid pressure control valve
    Patent number: 3982559
    Abstract: A fluid pressure operated control apparatus comprising a casing having an inlet and outlet for the flow of fluid under pressure, a diaphragm mounted in the casing having opposite sides thereof responsive respectively to outlet fluid pressure and a regulating pressure and valve means actuated by the diaphragm in response to pressure variations on its opposite sides for regulating outlet fluid pressure. The diaphragm is comprised of a main layer incompatible with high temperature pure steam and a protective layer. The layers are separable to provide for a contaminant fluid therebetween. The valve trim, including the valve head and stem, a valve stem guide and valve guide bushing having a snap-on valve seat, are insertable into and removable from the casing as an assembly, thereby providing for quick change of the valve trim.
