  • Patent number: 4582089
    Abstract: A valve manifold is provided of the type commonly referred to as an instrument manifold and used in systems designed to detect pressure differential. The manifold includes first and second passageways interconnecting a pair of input ports and a pair of output ports. Removable flanges are provided on the input and/or the output ends of the manifold. Each flange may be structurally secured to the valve manifold body by special nipples, and is provided with apertures for receiving bolts to mount the flanges to related process-side or instrument-side equipment. A threaded end of the nipple is adapted for sealing engagement with the manifold body, while the other end of the nipple is adapted for sealing engagement with elliptical-shaped flanges or a differential pressure transmitter. The versatility of the valve manifold is substantially increased, since the removable flanges allow the same manifold body to be used for either direct or remote mounting.

  • Patent number: 4480861
    Abstract: Apparatus for forming a sealed joint between juxtaposed, axially aligned pipe ends includes a pair of annular flange members slidable in facing relation on the pipe ends and having tapered annular interior surfaces converging outwardly of a central axis for forming an annular recess about the pipe ends. A resilient annular sealing gasket generally compatibly shaped with the recess is provided for disposition therewithin about the pipe ends. The gasket has a pair of tapered annular exterior surfaces which converge outwardly when uncompressed at slightly greater respective angles than the tapered interior surfaces of the flange members for respective sealing engagement thereby. A bolt arrangement draws the flange members axially together to compressibly engage the tapered exterior gasket surfaces between the tapered interior flange surfaces, thereby to compress the gasket against and between the pipe ends to seal them.
