  • Patent number: 9863542
    Abstract: A diaphragm valve with an assembly or cartridge that facilitates replacement of the diaphragm, the valve seat or both. The assembly may be a valve assembly having a diaphragm, a seat carrier and a valve seat that are combined into a discrete subassembly or cartridge for a diaphragm valve. The assembly as a discrete cartridge can be easily removed and replaced in order to change out the diaphragm or the valve seat or both. In one embodiment, the diaphragm has a perimeter that is welded to one side of the seat carrier. Flow capacity is favored by providing a gap between a seat carrier and a flow port of the valve body where the gap in part defines a flow area that is the same or greater than the flow area of the flow port. Methods for installing and replacing a valve assembly into a valve body are also disclosed.

  • Patent number: 9851032
    Abstract: A conduit fitting of the type having first and second threaded fitting components and at least one conduit gripping device, further includes a stroke limiting member that allows the fitting to be pulled up by applying a predetermined torque. In one embodiment, the stroke limiting member may be a non-integral torque collar and in another embodiment the stroke limiting member may be two engaging surfaces integrally formed with the fitting components. Alternatively, the fitting may also be pulled up by turns. In still another embodiment, a stroke limiting member is provided that may be used to enable a fitting that is designed to be pulled up by turns to also be pulled up by torque. The stroke limiting member facilitates many remakes of the fitting, including remakes by torque.

  • Patent number: 9835256
    Abstract: A valve includes a valve body, a valve seat, and a poppet assembled with the valve body. The poppet includes an axially extending poppet stem and a radially extending poppet sealing surface. The poppet is axially movable between a closed position and an open position. The poppet sealing surface is defined by a sealing member disposed on the poppet stem. The sealing member is laterally movable on the poppet stem. When the poppet is moved from the open position to the closed position, the sealing member is laterally moved to align the sealing surface with the seating surface.

  • Patent number: 9562635
    Abstract: A fitting for a tube or pipe capable of functioning a high pressures having a first fitting component adapted to receive the conduit end; a conduit gripping device such as a ferrule or ferrules and a second fitting component that can be joined to the first fitting component to cause the conduit gripping device to grip the conduit and seal when assembled. In one aspect of the invention, the first fitting component is constructed from a material that is softer than the material used to construct the second fitting component. An additional aspect of the invention include a retaining portion on the second fitting component that constrains the tube gripping device against pressure. The retaining portion can also be configured to retain the tube gripping device to the second fitting component prior to installation and in a finger-tight condition.

  • Patent number: 9383048
    Abstract: High localized loading, galling, and high torque forces have been generally eliminated or greatly reduced in a two ferrule tube fitting assembly through suitable modification of the rear ferrule so as to redirect the reaction forces acting between the front ferrule and the drive nut. The rear ferrule has a cylindrical interior wall that closely surrounds the tube end and is provided on the interior cylindrical wall with a circumferentially continuous radial recess that is located between the nose and rear wall of the rear ferrule. The rear ferrule also has a radially external wall that is substantially conical and additionally shaped to extend radially outward toward the enlarged diameter portion or flange of the rear ferrule.

  • Patent number: 9097622
    Abstract: A valve assembly includes a valve body having a fluid access passage extending from a process fluid port to an access port, a block valve disposed in the fluid access passage and movable between open and closed conditions, an access blocking device disposed in the fluid access passage between the access port and the block valve, and a valve interlock arrangement. The access blocking device is movable from an access blocking condition in which access to the block valve through the access port is blocked, to an access permitting condition in which access to the block valve through the access port is permitted. The valve interlock arrangement is configured such that the block valve is prevented from being moved to the closed condition when the access blocking device is in the access permitting condition.
