An outer surface of the substrate ring may form an inner surface of the substrate seal channel. An active component may be selected from a flow controller, a pressure transducer, a flow measurement sensor, a pressure regulator, a valve, and a flow meter. The active component may comprise a lower surface; a first component port in the lower surface; a component fluid passageway; a component ring; and a component seal channel formed in the lower surface and surrounding the component ring.

A valve plug adapted for sealing engagement with a seat ring. The valve plug includes a cylindrical body with an annular flange having a groove. A pair of bores is disposed in the body, each bore having a first diameter, a first end, and a second end disposed within the body. Each bore is also adapted to receive a fastener to couple the valve plug to a mounting portion, and a recess is disposed at the second end of the bore, forming a stepped portion. The recess is adapted to receive at least one of a portion of a retainer or a portion of the fastener. A sealing disk is disposed within the groove of the annular flange and is one of a machined sealing disk or a molded sealing disk.

A Control Valve Compensation System for producing both a pre-compensated and a post-compensated load sensing hydraulic directional control valve module, wherein both configurations use the same components except for a sliding compensating component. The Control Valve Compensation System generally includes a hydraulic directional control valve housing which is adapted to be easily-interchangeable between a load sensing pre-compensated pressure configuration and a load sensing post-compensated pressure configuration by simply removing and replacing a different compensator assembly within the housing. The compensator assembly is adapted to direct oil flow through the housing while simultaneously providing compensation for the valve function. Directional valve assemblies may be provided, with the valve assemblies functioning to provide post-compensated functions, pre-compensated functions, and mixed pre- and post-compensated functions. These directional valve functions can be re-configured in the field by simply swapping the compensator assemblies to produce the desired functionality of the end-user at that particular time.

A dual-purpose type gas-valve structure especially related to a gas-gun gas-valve used for controlling the igniting and releasing of gas. It is specially designed with the horizontal and vertical gas entrance types coexisting structure to facilitate selecting different types to insert and connect the high-pressure steel cylinder depending on the gun type. It mainly consists of a box-body set with several connected horizontal and vertical channels inside; wherein a group of vertically intersecting channels located below can respectively insert into the high-pressure steel cylinder from the horizontal entrance and the vertical entrance from outside; wherein the lower-layer horizontal channel located at the upper f-type channel belongs to the high-pressure gas control room and the touch-press port, and the gas can be thereby released to the vertical channel and strongly ejected out through the upper-layer horizontal channel to instantaneously propel and launch out the bullet of the connecting barrel.

A structure for forming a fluid path is provided. The structure for forming a fluid path according to one embodiment of the present disclosure includes a body configured with first and second fluid paths which communicate with each other, and a third fluid path which is provided at a position, at which the first and second fluid paths are connected to each other, and communicates with the first and second fluid paths, and includes one or more among a first ball which is able to be disposed in the first fluid path, a second ball which is able to be disposed in the second fluid path, and a third ball which is able to be disposed in the third fluid path, wherein a diameter of the first fluid path is greater than that of the second fluid path, and the second ball is able to be disposed in the second fluid path by passing the first fluid path.

A quick pressure reducer and cylinder valve for use with an SCBA includes a cylinder valve that connects to a pressure vessel, a pressure reduction assembly for reducing the pressure of breathing air provided by the pressure vessel, a probe, and an inlet/latch assembly. The probe includes a notch and a threadless probe tip, and the inlet/latch includes a corresponding receptacle and one or more latches adapted to fit into the notch to retain the probe in the receptacle. A pushbutton switch in the receptacle is triggered by insertion of the probe tip therein, thereby providing an electrical signal. Probes of different sizes may be used to correspond to different pressure capacities, and the inlet/latch assembly may be arranged either to permit the insertion of only one probe size or may be arranged to accept different sizes but to function differently based on the size of the probe. The latches are inoperable except at or below a nominal pressure.

An adjustable differential pressure control valve has a first housing part with one or more fluid entry openings and one or more fluid exit openings. The valve is provided with a movable throttle member configured for regulating the through flow area of the exit openings in response to a difference in pressure across the throttle member, and a spring arrangement configured for providing a spring force acting on the throttle member in a direction that increases the through flow area of the exit openings. The spring arrangement comprises at least a first and a second spring, and the spring arrangement is adjustable to operate in a low pressure mode with the spring force acting on the throttle member being provided by the first spring only, and to operate in a high pressure mode with the spring force acting on the throttle member being provided by at least both the first and second springs.
