A clamp assembly to secure a yoke to a valve body of a knife gate valve is provided. The clamp assembly can include a bolt that is configured to extend through a first bushing, a first spring member, a first side wall of the yoke, the valve body, a second side wall of the yoke, a second spring member, and a second bushing. The clamp assembly can be configured to pin the yoke to the valve body, apply a pressure-containing preload to the valve body via the first and second bushings, and compress the first spring member between the first bushing and the first side wall of the yoke and the second spring member between the second bushing and the second side wall of the yoke.

Floating yoke connection

Embodiments of the invention provide a knife gate valve for flow along a flow path. The knife gate valve can include a body structure that includes a gate passage, a gate disposed to move within the gate passage between open and closed positions to selectively open or close a fluid aperture, and a gate seat configured to engage a free end and lateral edges of the gate. A transverse element can be formed from resilient material and can extend laterally across the gate passage to form a seal with a first side of the gate and with the gate seat.

Sealing assembly for a knife gate valve

A gate valve can include a gate, a gasket seal, and a first body half that defines a first process fluid aperture. One or more replaceable rings can engage the first body half to secure or support the gasket, the gate, or another replaceable ring.

Gate supports for a gate valve

Embodiments provide a gate valve including a first body half that defines a first process fluid aperture, a first chest portion, and a first chest gate support recess formed in the first chest portion. A second body half defines a second process fluid aperture that is aligned with the first process fluid aperture, a second chest portion, and a second chest gate support recess that is formed in the second chest portion. A gate is movable relative to the first body half and the second body half. A first chest gate support is received within the first chest gate support recess, and a second chest gate support is received within the second chest gate support recess.

Embodiments provide a gate valve including a first body half that defines a first process fluid aperture, a second body half that defines a second process fluid aperture aligned with the first process fluid aperture, a gate that is movable relative to the first body half and the second body, and a first port gate support that is arranged on the first body half and extends into the first process fluid aperture. The first port gate support defines a curved surface that is configured to be in contact with a process fluid.

Port gate supports for a gate valve

Embodiments provide a gate valve including a first body half that defines a first process fluid aperture, a first chest portion, and a first gate support recess that is formed in the first chest portion. A second body half defines a second process fluid aperture that is aligned with the first process fluid aperture, a second chest portion, and a second gate support recess that is formed in the second chest portion. A gate is movable relative to the first body half and the second body half, and a gasket seal includes a flange portion, a body portion, and at least one cutout. The flange portion and the body portion are sized to be compressed between the first body half and the second body half, and the at least one cutout provides for volume transformation of the gasket seal under compression.
