    Abstract: 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.

    Abstract translation: 先导操作的减压阀包括具有流体入口的阀体和通过流体通道连接的流体出口。 阀塞可以设置在流体通道内，阀塞与阀座配合以控制通过流体通道的流体流动。 致动器可以连接到阀塞，调节器朝向阀座偏压阀塞。 导向组件可以包括第一先导阀和第二先导阀，其中先导组件将阀塞上游的流体压力引导到第一和第二先导阀之一。 当上游流体压力超过预定水平时，阀塞从阀座移开，允许流体流过流体通道。

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.
