Gate member for resilient-seated gate valve

A gate member for a gate valve provides improved sealing by providing for proper orientation of the gate member as it approaches its closed position and then providing improved sealing action as the gate member is closed further. A lip on the gate member overlaps a ledge on the valve body at the opening where the gate member enters the valve chamber. The lip is covered by a seal of resilient material having a cross-sectional shape that cooperates with the valve body to orient the gate member and that controls the compression of the seal between the lip and ledge as the gate member closes further. The shape of the gate member also helps to orient it while it is closing. A spine and a ridged cap of resilient material on the leading edge of the gate member cooperate to prevent blow-by of pressurized fluid when the gate member is closed. Pads integral with the seal contact the corners of the opening initially to orient the gate member and then to fill the corners when the gate member is closed ...

Shearing gate valve

A gate valve has downstream shear and seal capabilities in which the gate will stroke far enough to cover the downstream seat interface, and has a single shearing surface for shearing of a wireline. The gate has an inlay of a hard ductile material such as Stellite® along the shearing edge of the gate. The gate also has a coating of an extremely hard material such as tungsten carbide on the sealing surface of the gate. The seat also has an inlay of a hard ductile material such as Stellite® along its shearing edge. The gate fully covers and seals the upstream seat interface after the shear media has fallen below the upstream gate/seat interface. An upstream lip seal for the upstream seat ring is energized to seal on upstream pressure.

Slide Valve, in Particular for Blocking a Line Conveying Media

A slide valve, in particular for blocking a line conveying media, is provided with a housing ( 2 ) having a passage opening ( 3 ) and with a slider plate ( 4 ) moveable within the housing ( 2 ) at right angles to the passage opening ( 3 ). The latter can be displaced from an open position into a closed position blocking the passage opening ( 3 ) tightly by means of a drive mechanism ( 10 ). A lateral seal ( 20 ) is respectively disposed in a respective groove ( 20′ ) in the housing ( 2 ) above the passage opening ( 3 ) on both sides of the slider plate ( 4 ) at right angles to its direction of displacement. The inside and outside of the housing ( 2 ) and the slider plate ( 4 ) are provided with at least one layer forming a temperature barrier, and the lateral seal comprises a high temperature-resistant layer or sealing compound. The risk of a leak into the atmosphere and/or in the passage during a fire or during extinguishing efforts is thus substantially reduced.

Pipeline control unit

A pipeline control unit that joins pipeline conduits and has a housing with an interior compartment for receiving a gate. A valve servicing assembly or pressure plates can be installed onto the housing to form a fluid tight structure to allow removal and replacement of a retained gate without depressurizing a pipeline system. Strongbacks attached to the housing can compress lateral walls of the housing to secure a gate in the interior compartment, and removal of such compression allows removal of the gate while the pipeline is pressurized.
