A self-centering valve adapter connection assembly includes a first equipment flange that is connected to a second equipment flange with an adapter ring. The adapter ring includes a first longitudinal flange with a tapered inner surface and a cylindrical outer surface. The adapter ring aids in centering the first and second equipment flanges while smoothing a fluid flow corridor between the first equipment flange and the second equipment flange.

A trapezoidal thread form includes a thread having a trapezoidal cross-sectional shape, the thread including an apex surface, two side surfaces, and a valley; and a thread wear indicator formed in one of the apex surface and one of the side surfaces. The thread wear indicator may include a v-shaped channel formed in one of the apex surface and one of the side surfaces or the thread wear indicator may include a series of material layers, each layer having a physical characteristic that is different from an adjacent material layer. The thread wear indicator indicates excessive or unsafe thread wear when the v-shaped channel is indistinguishable from the apex surface or the side surface, or when a first layer wears sufficiently to show a second layer.

Cam apparatus for use with valves are disclosed. An example apparatus includes a cam having a cam surface to engage a valve stem, a first portion of the cam surface to engage the valve stem in a closed position, a second portion of the cam surface to engage the valve stem in an open position, and a third portion of the cam surface adjacent the first portion and defining a curved profile. The third portion is to engage the valve stem when the cam is rotated to a first intermediate position between the closed position and the open position. The example apparatus also includes a fourth portion of the cam surface between the second portion and the third portion and defining a linear profile. The fourth portion is to engage the valve stem surface as the cam rotates between the first intermediate position and the open position.

Cam apparatus for use with valves

A valve assembly for use in a piping system includes a valve having an inlet and outlet arranged for connection to the piping system, and further includes a valve body, a control element disposed in a flow passage, and a shiftable valve stem operatively coupled to the control element. Valve packing is disposed about the valve stem and is secured by a retainer assembly. An adapter plate is provided and is attached to the valve body by a plurality of gland bolts, with the adapter plate and the gland bolts cooperating to secure the retainer assembly. An actuator bracket is provided and includes a first portion and a second portion, with the first portion secured to the adapter plate by a plurality of fasteners, and an actuator is secured to the second portion of the actuator bracket by a plurality of fasteners, with the actuator having a control rod operatively coupled to the valve stem.

A pilot operated pressure relief valve includes a valve body having a fluid inlet and a fluid outlet connected by a fluid passageway. A valve plug may be disposed within the fluid passageway, the valve plug cooperating with a valve seat to control fluid flow through the fluid passageway. An actuator may be connected to the valve plug, the regulator biasing the valve plug towards the valve seat. A pilot assembly may include a first pilot valve and a second pilot valve, wherein the pilot assembly directs fluid pressure upstream of the valve plug to one of the first and second pilot valves. When the upstream fluid pressure exceeds a predetermined level, the valve plug moves away from the valve seat allowing fluid to flow through the fluid passageway.

A fluid regulator includes a regulator body having a fluid inlet and a fluid outlet connected by a fluid flow path, with a portion of the regulator body forming a first chamber and a second chamber, an orifice disposed in the fluid flow path, a seat, and a control element disposed within the fluid flow path and shiftable between an open position spaced away from the seat and a closed position seated against the seat, with the control element arranged to respond to fluid pressure changes to control flow of a process fluid through the orifice. A first diaphragm having a radially inner portion is operatively coupled to the control element, and a second diaphragm having a radially inner portion also is operatively coupled to the control element.
