The door is configured to cover an opening of the tee body, wherein an end of the door unconnected to the arm is pivotally connected proximate the rear side of the tee body.

Abstract: A valve assembly has a valve body, a lower bushing, a valve seat, a lower stem, a disc, and an upper stem. The valve body defines a bi-directional flow path therethrough; wherein the valve body has an inner surface, two flange faces, and further defines an upper orifice and a hemispherical lower orifice along an axis perpendicular to the flow path. The lower bushing is housed in the lower orifice, and the lower bushing is configured to tilt within the lower orifice away from the axis. The lower bushing defines a bushing cavity. The valve seat has an outer surface configured to encapsulate the inner surface and the two flange faces of the valve body. The lower stem is housed in the bushing cavity, and the lower stem is configured for tilting away from and towards the axis perpendicular to the flow path. The disc has a seating surface on at outer circumference, defines a stem receptacle to house the lower stem, and the stem receptacle extends less than a diameter of the disc.

Abstract: The disclosure relates to an embodiment of a valve position indicator having an indicator cover having at least one window and a rotor configured to be at least partially within the indicator cover. The rotor has an indicator surface with one or more position indicators wherein at least one of the position indicators is configured to align with the window on the indicator cover, thus indicating the position of a valve. A light may be positioned proximate the rotor and configured to illuminate the position indicator. The valve position indicator may also include an array of LED lights bordering the rim of the indicator cover. The valve position indicator may alternatively include the array of LED lights without the indicator cover.

Abstract: In an angle valve, an externally threaded sleeve within the yoke surrounds the stem at an upper end of the stem. A yoke bushing fixed to the valve has internal threads matching with the external threading of the sleeve. A split collar assembly is located on the stem above the sleeve. The stem has a greater diameter itself, and/or via a nut, at a lower portion of the stem (below the sleeve) relative to the upper portion of stem. The plug stem is designed to pass through the yoke bushing making it possible to perform the normal open-close operation and grinding operation independently.
