    Abstract: An assembly includes a housing along a fluid line through which gas can flow with the housing having an annular shape, a housing groove extending circumferentially around a radial interior, and a sense hole adjacent the housing groove in a bottom side of the housing; and a piezometer ring disposed within the housing groove and coaxial with the housing. The piezometer ring includes a ring groove extending circumferentially around a radially outer side adjacent the housing and a plurality of ring holes extending radially through the piezometer ring with the plurality of ring holes including two bottom holes closest to the bottom side of the housing that are spaced farther apart from one another than from adjacent holes of the plurality of ring holes.

    Abstract: A manual positioning assembly for connection to a shaft of a valve configured to manually manipulate a disc of the valve between an open and closed position. The manual valve positioning assembly includes a housing having a first and a second end. The first end includes a flange configured for fastening the housing to the valve. The second end includes a conical feature. An alignment bushing within the second end of the housing and a double universal joint. The double universal joint includes a first end and a second end. The first end of the double universal joint is configured to be mechanically fastened to the shaft of the valve. The second end is positioned within the alignment bushing and includes a socket configured to receive a tool that manually turns the double universal joint, the shaft, and the disc to position the disc in the open or closed position.

    Abstract: An intermediate thrust plate is provided to absorb thrust loads while permitting rotation and deflection of a butterfly valve shaft. The intermediate thrust plate includes a body having upper and lower surfaces and defining an aperture extending through the body between the upper and lower surfaces, the upper surface extending annularly about the aperture and being substantially flat, the lower surface extending annularly about the aperture and having a spherical shape and at least the lower surface including a low-friction material.

    Abstract: An example embodiment of a filter for a butterfly valve includes an inlet side having an axial inlet port and the first diameter Din, a closed outer side having a second diameter D2, and a filter body disposed between the inlet side and the outer side. The filter body has a filter diameter Dfilter larger than both Din and D2, and includes a cylindrical wall retaining a pleated filter media. A plurality of perforations is formed through a main bore wall to serve as at least one exit for the filter.

    Abstract: A bleed valve system includes a bleed valve, a valve regulator, a valve actuator and a reverse flow relief valve. The bleed valve is opened and closed to control a flow of bleed air from an upstream inlet to a downstream outlet. The valve regulator provides a servo pressure used to regulate the position of the bleed valve, and the valve actuator is mechanically connected to open/close the bleed valve based on the servo pressure provided by the valve regulator. The reverse flow relief valve compares a pressure upstream of the bleed valve to a pressure downstream of the bleed valve and in response to the downstream pressure exceeding the upstream pressure creates a fluid communication path between the servo pressure and an ambient pressure to decrease the servo pressure such that the bleed valve is closed.

    Abstract translation: 泄放阀系统包括排放阀,阀调节器,阀致动器和逆流溢流阀。 泄放阀被打开和关闭以控制从上游入口到下游出口的排出气流。 阀调节器提供用于调节放气阀位置的伺服压力,阀门执行器机械连接,以根据阀调节器提供的伺服压力打开/关闭排气阀。 反向泄流阀将排放阀上游的压力与泄放阀下游的压力进行比较,并且响应于下游压力超过上游压力,在伺服压力和环境压力之间形成流体连通路径,以降低伺服压力 使得排气阀关闭。
