An asymmetrical ram button is provided. In one embodiment, a system includes a blowout preventer including such a button. Particularly, the blowout preventer may include an actuation assembly having the asymmetric ram button attached to a connecting rod coupled to a piston. The asymmetric body of the button can engage an internal shoulder of the ram such that a retraction force on the actuation assembly causes the asymmetrical ram button to load against the internal shoulder. Additional systems, devices, and methods are also disclosed.

In at least some implementations, a solenoid valve includes a housing, a bobbin and an armature. The bobbin is received at least partially within the housing and has a body about which a coil is provided. A fluid flow path including an inlet and an outlet and a valve seat is defined by at least one of the housing or the bobbin, and the armature is moveable relative to the valve seat to control flow through the fluid flow path.

The present invention relates to a boltless bonnet assembly for use in a blowout preventer (BOP). In some embodiments, the boltless bonnet assembly includes a bonnet having a forward end facing a ram body of the BOP stack, and a bonnet latch disposed within the bonnet, the bonnet latch attached to the forward end of the bonnet. The boltless bonnet assembly further includes a bonnet positioning mechanism in communication with the bonnet latch to move the bonnet latch into and out of engagement with the ram body.

A non-return valve fitted on a tubular element for use for the reinforcement and consolidation of soil, for example, in an excavation. The non-return valve includes a portion of elastomer material which has a nick and is connected to a structural body tightened onto the tubular element. The structural body can be connected rigidly to the portion of elastomer material or may be at least partially incorporated therein. The body has a central portion with a window within which the nick is arranged, and the edges of the nick open out and function as a non-return valve under the action of a fluid under pressure injected into the interior of the tubular element and emerging from radial holes in the vicinity of the nick.

A valve and method for producing a valve for regulating a fluid, the valve including a valve housing with a central part and two connection ends, the connection ends extending away from the central part. Internally of the central part, there is arranged a valve body with a through-going aperture that is arranged in a valve seat and connected to a valve spindle, the valve spindle being arranged in a spindle guide stub on the valve housing. The valve housing is made from a plastically deformed tubular item and includes a collared spindle guide stub with at least one projection, the projection or projections extending in continuation of the spindle guide stub. This projection can be used as a lock ensuring that the valve spindle is retained in its intended position, and at the same time, such projections can form stops at the extreme positions of the valve body.

A solenoid assembly (100) is provided that includes a frame (104), a coil (106) positioned proximate the frame (104), and a core (114) defined by the coil (106). A plunger (108) is actuatable between at least a first position and a second position, and a guide (109) is at least partially disposed within the core (114). The plunger (108) is disposed at least partially within the guide (109). A housing (102) at least partially houses the frame (104), the coil (106), the guide (109) and the plunger (108), and the guide (109) is prevented from rotating independently of the housing (102).

Disclosed is a water manifold that provides a sturdy platform for both distributing water to various other locations or nodes and providing a support platform for a yard hydrant. The manifold is constructed of plastic and will not corrode. Further, the manifold is sturdy and provides a sufficiently large surface area to prevent sinking or tilting of the yard hydrant.

A pressure relief valve is disclosed with a first stage valve that is in series with a second stage valve, with an enclosed cavity between the first stage valve and the second stage valve. The first stage valve relieves pressure from an enclosure into the enclosed cavity between the stages, when the pressure is above a cracking pressure of the first stage valve. The second stage relieves pressure from the enclosed cavity when the pressure is above the cracking pressure of the second stage valve.
