Embodiments described herein relate to a pressure-regulating device, systems that include the device, and related methods. For example, the pressure-regulating device may receive gas from a gas supply at a first pressure (e.g., on a supply side of the pressure-regulating device) and may regulate or reduce the pressure of the received gas to a selected or suitable second, different pressure.

A valve positioner for use on a process control valve or “valve assembly.” The process control valve may include a pneumatic actuator and a valve having a closure member coupled with the pneumatic actuator and moveable relative to a seat. The valve positioner may couple to the pneumatic actuator to provide a pneumatic signal to set a position of the closure member relative to the seat. An accelerometer may couple with the valve positioner. The accelerometer may generate data in response to orientation of the valve positioner. In one implementation, the configurations can use this data to ensure proper visualization of data on a display. The data also permits the device to properly manage operating modes, like tight shut-off or fully-opened mode, that may prevail due to orientation issues that cause defects in a measured position for a closure member that regulates flow of material through the valve assembly.

A semiconductor device manufacturing system and a method for manufacturing semiconductor device are provided. The semiconductor device manufacturing system comprises a valve box module, a controller, a purge gas source and at least one semiconductor manufacturing tool. The valve box module includes at least one stick and a first gas line in fluid communication with the at least one stick. Further, the first gas line includes a pneumatic valve and a pressure transmitter downstream of the pneumatic valve. The controller connects to the pneumatic valve and the pressure transmitter of the first gas line. The purge gas source is in fluid communication with the first gas line. The at least one semiconductor manufacturing tool is coupled to the at least one stick.

A priming valve includes a fluid flow path, a fluid inlet configured to couple to a fluid outlet of a fluid channel including at least one sensor configured to characterize at least one attribute of a fluid, a fluid outlet, a valve seat, and a connector. The connector engages the valve seat to prevent fluid flow via the fluid flow path. The connector is configured to move relative to the valve seat in response to a threshold pressure within the fluid flow path to allow the fluid to flow via the fluid flow path. A flow sensor sub-assembly for sensing flow of a fluidic medicament may include a priming valve and at least one sensor of a fluid port configured to characterize at least one attribute of a fluid within an administrable fluid source. A method for readying a fluid sensor may use a priming valve.

A method of controlling the discharge of waste water from a toilet includes the installation of a valve in the discharge outlet of the toilet, the valve including a valve body and a spring-loaded valve closure member that is movable relative to the valve body into an open position during flushing of the toilet against the action of its spring-loading and which is returned to the closed position by the action of its spring-loading on completion of the flushing operation.

A linear actuator includes a jacket defining an axis, and a rod having an end cylinder tightly slidable within the jacket and an opposite end sliding between a rest position and a working position. The end cylinder divides the jacket into a first and second variable volume compartment fluidically independent from each other, one of the first or second variable volume compartment being fluidically insulated and under vacuum, the other one fluidly communicating with the outside environment. The jacket has an abutment member having a non-return valve mechanism adapted to discharge ambient air that may be entrapped between the end cylinder and the abutment member.

A fluid flow control unit, in a preferred embodiment, mounted on a section of pipe having a tubular wall forming a fluid flow passage with a flow axis, the unit having a gate section, and a gate pivot section, the pivot section having a body portion mounted on the pipe outer wall surface, a gate mounting cavity formed in the body portion and opening through the pipe wall and providing an access port for the gate section to the mounting cavity, a pivot shaft positioned in the cavity and mounted on bearing structure on the body portion, the diameter of the shaft being dimensioned to allow a laterally curved gate which is affixed to a surface portion of the shaft to pivot up against a ceiling of the pipe to thereby be out of the flow passage main stream at a full open, non-blocking position of the gate, and a gate position control structure on the unit for allowing predetermined degrees of rotation of the pivot shaft in response to the magnitude of fluid flow pressure forces directed against the gate.
