A hybrid pressure and flowguage regulator apparatus includes a regulator body, an inlet, and an outlet assembly. The outlet assembly includes a first orifice of a first size, a second orifice of a second size that is larger than the first size, and a mechanism that automatically moves the first orifice between a first position and a second position. When the first orifice is in the first position, the flow of gas passes through both the first orifice and second orifice. When the first orifice is in the second position, the flow of gas bypasses the first orifice and flows through the second orifice with a specific flow rate or a second pressure that is less than the first pressure. The apparatus may also include a gauge that provides a visual indication of both the specific flow rate and the second pressure.

A high integrity protection system includes a flow line including an inlet configured to be connected to a first source of pressure and an outlet configured to be connected to a downstream system. A first subsystem is installed on the flow line between the inlet and the outlet. A second subsystem is installed on the flow line between the inlet and the outlet, and the second subsystem is in a parallel flow configuration in relation to the first subsystem. The system includes a second source of pressure configured to be fluidically connected to the first subsystem and the second subsystem.

A fuel storage assembly for a vehicle includes a fuel tank defining a fuel chamber, a fuel pump module and a vapor pressure detection system. The fuel pump module includes a flange engaged to the fuel tank and a fuel pump assembly supported by the flange and disposed in the fuel chamber. The vapor pressure detection system includes a vapor pressure sensor attached to the flange, a vapor pressure inlet device disposed in the fuel chamber, and a conduit communicating between the vapor pressure inlet device and the vapor pressure sensor.

A system includes a pre-assembled, modular valve assembly configured to be coupled to both an industrial gas appliance and a fuel supply system for the industrial gas appliance. The system includes a manual isolation valve, a first block valve, and a bleed valve. The modular valve assembly is configured to be disposed at a location separate from the industrial gas appliance.

A balancing valve for adjusting the flow rate of a fluid flowing inside a pipe from upstream to downstream in a longitudinal direction of flow. The balancing valve includes: a check valve and a tubular element simulating a Venturi tube, said valve and element being coaxially connected, respectively, from upstream to downstream in the longitudinal direction of flow of the fluid; a device for detecting the difference in pressure which occurs inside the valve; a valve for adjusting the flow rate of the fluid which flows inside the pipe; wherein: the detection device is arranged between the inside of a first upstream chamber of the check valve and the inside of a central cylindrical portion of the tubular element.

The subject of the present invention is a valve for extracting, by pumping, a fluid contained in a space, said valve comprising: a) a main body having a first opening for the passage of said fluid during pumping, and b) an indicator means configured to indicate whether or not the fluid is passing through the first opening.

The present disclosure generally relates to a manifold valve assembly engaged to an inflatable apparatus, such as a cushion to prevent pressure ulcers, for example. The manifold valve assembly is also in communication with a processing device to determine an optimal immersion level for a user seated on the inflatable apparatus. Additionally the processing device, in communication with the manifold valve assembly may save optimal immersion or air pressure levels for comparison to future checks of cushion pressure and send that to a user interface at the processing device. The assembly and processing device may also save and display a history of pressure checks.

A system includes a client application executed by a client computing device for setting up an inflation level and checking an inflation level of an inflatable cushion having at least one air cell or zone and at least one pressure sensor within the cushion that detects air pressure. The client computing device communicates with the inflatable cushion and determines an optimal inflation level for a user of the inflatable cushion.

A high temperature warning system for a vehicle steer axle an air pressure supply, a normally-closed valve in fluid communication with pressure supply, a heat sensitive control capable of opening the normally-closed valve upon a predetermined temperature, the heat sensitive control mounted adjacent to the wheel end assembly in a heat exchange relationship therewith, and a warning system connected to the air pressure supply for actuation upon opening of the normally-closed valve.
