A valve assembly includes an actuator adapted to drive movement of a valve member between an open position and a closed position. The valve assembly also includes a bonnet coupled to the actuator and a valve body coupled to the bonnet, the bonnet arranged between at least a portion of the actuator and the valve body. The valve assembly further includes a quick connector adapted to couple the bonnet to the valve body. The quick connector includes a plurality of bonnet lugs separated by a plurality of spaces, the plurality of bonnet lugs extending radially outward from an axis. The quick connector also includes a plurality of valve body lugs configured to interact with the plurality of bonnet lugs, the plurality of bonnet lugs being arranged to axially align with the plurality of valve body lugs to block axial movement of the bonnet with respect to the valve body.

No-bolt valve assembly system

A quick connect coupling mechanism joins an actuator to a bonnet. The quick connect coupling mechanism may utilize machined or otherwise prepared components including one or more specific features, such as slots or grooves, to facilitate a connection between the actuator and the bonnet. For example, the actuator housing may be machined or formed to include an opening to enable radial insertion of the bonnet into a slot formed circumferentially about at least a portion of the actuator housing. The opening may be secured to block radial movement of the bonnet within the housing. A rail system may also be utilized to couple the actuator housing to the bonnet. For example, pairs of grooves may be formed in the actuator housing and bonnet to facilitate insertion of rails. The rails may block both axial movement of the actuator housing and also block rotational movement.

Quick connect actuator

A system includes an actuator housing having a plurality of adapter lugs extending radially inward toward an axis, each adapter lug of the plurality of adapter lugs secured to the housing via a respective connector. The system also includes a bonnet having a plurality of bonnet lugs extending radially outward away from the axis, each bonnet lug of the plurality of bonnet lugs being separated by a respective space, the space being sized to permit axial movement of an adapter lug of the plurality of adapter lugs toward a lower flange arranged axially lower than the plurality of bonnet lugs.

No-bolt latching system

A system for securing a valve actuator to a valve assembly includes an actuator housing with a plurality of housing lugs protruding radially. A cylinder assembly is located within the actuator housing and has a horseshoe connector to engage a valve stem nub of a valve stem and transfer axial movement of the horseshoe connector to axial movement of the valve stem. A bonnet has a plurality of bonnet lugs protruding radially from the bonnet to define a plurality of bonnet slots therebetween, wherein each of the plurality of housing lugs are sized to pass axially through a respective one of the plurality of bonnet slots when the actuator housing is in a released position, the actuator housing being rotatable to a locked position such that the plurality of bonnet lugs prevent axial movement of the actuator housing in at least one direction.

A valve with a packing assembly can include a first stem packing circumscribing a first portion of a valve stem, forming a seal between the valve stem and a valve body assembly, and being located in the second bore portion. A first packing retainer can have a collar that limits axial movement of the first stem packing and a first retainer body defining an inner cavity. A second stem packing can circumscribe a second portion of the valve stem and be located in the inner cavity of the first packing retainer. A second packing retainer can limit axial movement of the second stem packing. A piston member can be located axially between the first stem packing and the second stem packing, the piston member being moveable to apply axial force to one of the first stem packing and the second stem packing.

A valve with a packing assembly includes a valve body assembly with a bore, a valve member moveable between an open position and a closed position, and a valve stem coupled to the valve member. A first stem packing circumscribes a portion of the valve stem, and is located in an upper bore portion of the bore. A first packing retainer has a collar that limits axial movement of the first stem packing, and also has a first retainer body defining an inner cavity. A second stem packing circumscribes a portion of the valve stem and is located in the inner cavity of the first packing retainer. A second packing retainer has a neck compressingly engaging the second stem packing, and a retainer shoulder that engages the first packing retainer. A retaining assembly is coupled with the valve body assembly for applying axial force to the second packing retainer.

A split gate is movably mounted within a valve body along a valve axis between valve seats. The split gate has gates, each extending between one of the valve seats and the other gate. In an open position, gate holes register with a fluid aperture and the valve seats to permit fluid flow. In the closed position, the holes do not register with the fluid aperture to prevent fluid flow. The split gate valve also has a gate guide located in the body for moving the gates with respect to the valve seats along the fluid axis. The gate guide forces the pair of gates apart along the fluid axis and into contact with the valve seats in both the open and closed positions. The gates have axial play along the fluid axis when the split gate is between the open and closed positions.

A gate valve has seat rings pressed into counterbores to form seals. Each counterbore is located at an intersection of a flow passage with a central cavity of a body of the gate valve. The counterbore has a cylindrical constant diameter sidewall. The seat ring has an outer end that forms a pilot section and is of smaller outer diameter than the inner diameter of the counterbore. The seat ring also has an outer portion that is of equal or larger diameter than the inner portion, defining an interference section. The interference section creates an interference fit with the counterbore, forming a seal.

Interference-fit seal for gate valves

A lock pin for locking a pipe hanger assembly in a wellhead is hydraulically actuated. The lock pin extends through a radial passage provided in the wellhead. The lock pin moves linearly to an inner position to engage the hanger assembly. A hydraulic piston is coupled to the exterior of the wellhead for providing an inward force to the lock pin. A retainer is mounted to the wellhead by threads. While the lock pin is held in the inner position under hydraulic pressure, the retainer is rotated inward against a shoulder provided on the lock pin to hold the lock pin in the inner engaged position. The hydraulic pressure can then be removed.
