A multi-stage pressure regulation system, device and associated methodology for reducing the pressure of gas passing through a gas sample conditioning system. The device and method allow for automatic and/or manual configuration settings for regulating different types of gas having different profiles while still avoiding dew point dropout thereby ensuring accurate sample analysis at a downstream analyzer. The pressure regulating device includes a housing having a core, a vapor sample input port, a plurality of openings on an upper surface, a plurality of pressure regulating valves configured to reduce the pressure of a vapor sample, and an assembly having a base and substantially central stem orthogonal to the base and extending axially therefrom, the stem being disposed within the core.

An actuator includes a guide that extends in one direction and a slider that is movable in an axial direction with respect to the guide. Either the guide or the slider has a recessed cross-section, and the slider is guided by the guide while the other of the guide and the slider is restrained by three surfaces constituting the recessed cross-section.

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.

The following disclosure relates to a valve assembly for allowing filling and draining of a container with a liquid, preferably for use in growing plants, the valve comprising: a filling catchment containing at least one opening for receiving liquid and at least one drainage orifice, the filling catchment being located within the container; a draining outlet adapted to convey liquid out of the container; a plugging member configured to move between a first position where the plugging member allows liquid to flow into the draining outlet and a second position where the plugging member prevents liquid from flowing through the draining outlet; and a biasing member which acts to retain the plugging member in the first position unless a force is applied above a predetermined value. Also provided are systems including and methods of using said valve assembly.

A valve system for driving fluid and a method for using the same are provided. The valve system includes a fluid unit far away from the rotation center, a fluid unit close to the rotation center, a fluid transferring unit and a gas path pipeline for communicating the fluid unit close to the rotation center with the fluid unit far away from the rotation center. A rotation radius of a fluid outlet of the fluid unit far away from the rotation center is greater than that of a fluid inlet of the fluid unit close to the rotation center. The fluid outlet of the fluid unit far away from the rotation center is located at an end thereof away from the rotation center, and the fluid inlet of the fluid unit close to the rotation center is located at an end thereof close to the rotation center.
