A bonnet assembly may be coupled to a valve block. The bonnet assembly may include a bonnet body extending, in an axial length, between a first and second end of the bonnet body. Additionally, the bonnet body may have a sealing surface on the second end. Further, a bonnet retainer nut may be provided with passage axially extending through a first end surface to a second end surface. The bonnet retainer nut may be disposed on the bonnet body such that a portion of the bonnet body is enclosed within the passage of bonnet retainer nut. Furthermore, the bonnet retainer nut may lock the bonnet body.

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.

The present disclosure provides a modular linear actuated valve having a lower body module that can interface with an interchangeable upper linear actuator module being at least one of a mechanical linear actuator module and a fluid linear actuator module. The invention includes a quick disconnect between the body module and any of the actuator modules. An actuator assembly on the selected actuator module can be coupled to the valve stem on the lower body module using a quick disconnect segment on the actuator module and a reciprocal quick disconnect segment on the body module. A valve can be quickly converted into a mechanical linear actuated valve or a fluid linear actuator valve, simplifying manufacturing and stocking, and providing a faster response to customer orders.

A sealing ring made of an elastomer material is fitted on the front side of an essentially rectangular valve plate for sealing a vacuum valve opening. On the rear side, the valve plate has a recess with an undercut boundary wall which forms a sloping surface which, for fastening the valve plate on a carrier, is braced with a sloping surface of the carrier. The valve plate has a lug which protrudes beyond the rear side thereof and has a through-passage bore through which a clamping screw is screwable into a threaded bore of the carrier, for bracing the valve plate sloping surface with the carrier sloping surface. In a side view of the valve plate, seen parallel to the longitudinal sides, the straight-line extension of the longitudinal center axis of the through-passage bore runs past the sloping surface at a distance from the rear side of the valve plate.

Aspects of the present disclosure relate to valve skid apparatus and related methods for wellhead systems. A check block of the check valve includes a check side face that interfaces with a gate side face of a gate block of the gate valve. A pump side block is coupled to the gate valve, and a well side block is coupled to the check valve. A first pressure relief valve is coupled to a top face of the pump side block, and a first bleed-off valve is coupled to a top face of the first pressure relief valve. A second pressure relief valve is coupled to a top face of the well side block, and a second bleed-off valve is coupled to a top face of the second pressure relief valve.

A slide gate includes a gate body defining a first gate face and a second gate face; and an integral gate seal integrally formed with the first gate face, the integral gate seal comprising an additive material additively deposited on the first gate face, the integral gate seal defining a gate seating face.

The invention relates to a slide valve (20) having a slide valve plate (32) movable in a slide valve rail (29) between a locked position and an open position in a slide valve casing (26), said slide valve rail (29) being provided with a slide valve seal for attaining a gas-proof locked position, said slide valve rail (29) being connected to the slide valve casing (26) via a flange connection in such a manner that the slide valve rail (29) is removable from the slide valve casing (26) radially to a flow axis of the slide valve (20).

A push joint adapter is connectable to one or more push joint pipe fittings in a pipeline. The push joint adapter includes an insertion section insertable into a socket of a push joint pipe fitting in an interference fit, a pipeline section connectable with the pipeline, and a collar disposed between the insertion section and the pipeline section. A restraint ring assembly cooperable with the push joint pipe fitting includes a restraint ring secured to the pipeline section and engaging the collar and a restraint rod connected to the restraint ring. The push joint adapter facilitates connecting push joint gasketed bell gate valves and fittings in a pipeline such as a polyethylene pipeline.

Pipeline apparatus comprising a housing including a riser and a pipeline connector and a device configured to interact with fluid flowing through the pipeline connector, a mounting means for releasably mounting the device in the riser and seal means situated between an inner surface of the riser and an outer surface of the mounting means, the seal means configured to seal against egress of fluid from the apparatus, the mounting means and the riser each including a part of a locking means for releasably locking the device in the riser, the device situated in the pipeline connector.

A faucet device includes: a base member; an outer shell member; a metallic casing member that is inserted in a columnar section of the outer shell member and whose one end is fixed to the base member; a hot-water supply pipe and a cold-water supply pipe that supply hot water and cold water, respectively; a single lever cartridge provided at the other end of the casing member; connecting members provided inside the casing member, connecting the hot-water supply pipe and the cold-water supply pipe to the single lever cartridge; a fixing member fixing the single lever cartridge to the connecting members; and mechanical engagement pins. The casing member is formed of a metallic plate or pipe with a size that allows the casing member to be insertable into the columnar section of the outer shell member, and capable of retaining the connecting member in accordance with the mechanical engagement means.
