A touchless tap handle for beverage dispensing is provided that incorporates a spring and ball check valve within a spigot housing. The spigot housing as a male threaded end for connection to a beverage dispensing line. Between the beverage connection and the check valve is a flow control valve having a detachable control mechanism. A system operator can use the control mechanism to calibrate fluid flow. The control mechanism is further fastened or keyed to allow for removal after modifying system flow parameters. A tap handle extension is further provided that can be threadingly affixed to the spigot housing. The tap handle extension specifically does not control operational parameters, which are intended to be initiated through pushbutton control of a pour control system.

This circuit breaker (10) for a facility for handling pressurized fluid includes a male element (100) and a female element (200) intended to fit in one another. The male element includes a male body (102) defining a first inner pipe (104) and provided with a member for closing off the front end of the first pipe, along the fitting axis, of at least one first radial passage (116), of a movable valve (118) and a locking notch arranged on the male body. The female element includes a female body (202) defining a second inner pipe (204A) and provided with at least one radial passage (256), a movable valve (218) and several locking members (242) movable transversely with respect to the fitting axis, between a first radial position, for the axial locking of the male and female bodies in the coupled configuration, and a second radial position, where the locking members free the passage of the male body (102) in the female body (202). In the coupled configuration, the radial passages (116, 256) are in communication, while sealing gaskets (266, 268) respectively cooperate radially with the male and female bodies (102, 202). A resilient return ring (246) is mounted on the female body (202) and surrounds the locking members (242). This ring resiliently returns the locking members toward their first radial position in the coupled configuration and is deformed radially, and resiliently, by the locking members during their movement, from their first radial position toward their second radial position.

A check valve supplies fluid to a system and includes a fluid barrier protects the sealing elements and surfaces of the check valve preventing degradation from any backflow of gas and debris from the system to which fluid is supplied.

A device for collecting air into an air collecting pipe through a hole having a certain size includes a diaphragm check valve having elasticity. The diaphragm check valve is opened due to a change in the pressure in the vicinity of an air layer during generation of air when gas accumulation occurs in a safety related system pipe of a power plant or in a general pipe.

The invention relates to a pressure control valve, composed of at least a valve component; situated between a control chamber and a return chamber, the valve component has an orifice, which a control element can close, partially close, or open, and the control element has at least one, at least truncated cone-like first control element region with a truncated cone angle and the orifice is formed by a through opening, which extends through the orifice element and at its end oriented toward the control element, has at least one cone-like, in particular first, orifice region with a cone angle; and the cone angle is greater than the truncated cone angle.

The invention relates to a gas regulating valve (1) for a respiratory system comprising:a main path between an inlet (2) and an outlet (3), andan evacuation path between the outlet (3) and an evacuation orifice (4), characterised in that:the main path is provided with at least a non-return valve for preventing gas to circulate from the outlet (3) to the inlet (2), andthe evacuation path is provided with an obstructing membrane (10) arranged and designed for being deformed by gas from the inlet (2) to partially or fully obstruct the evacuation path. The invention also relates to a mask integrating such gas regulating valve, and to a respiratory system also comprising such gas regulating valve.

A tap handle extension is further provided that can be threadingly affixed to the spigot housing. The tap handle extension specifically does not control operational parameters, which are intended to be initiated through touchscreen or pushbutton control of a pour control system.

A valve assembly includes a valve housing having an internal generally cup-shaped bore, a valve control cartridge inserted into the bore and having a rotatable control stem extending upwardly therefrom, and a bonnet nut having a through-bore. The bonnet nut is threaded to the valve housing such that the control stem extends through the through-bore. Flexible fingers are provided along the through-bore to control a level of resistance to a rotation of the rotatable control stem. The stem is positioned to frictionally engage the flexible fingers as the stem is rotated.

A control valve (4) for controlling pressure medium flows of a camshaft adjuster which includes a substantially hollow cylindrical valve housing (6), a control piston (12), which is guided axially displaceably inside the valve housing (6), and a non-return valve (22) which can be hydraulically released. In a region of a pressure medium inlet, the valve housing (6) includes a housing shaft (28) with an axial inflow bore (30) which widens in funnel-like manner towards the inlet side.

A check valve supplies fluid to a system and includes a fluid barrier protects the sealing elements and surfaces of the check valve preventing degradation from any backflow of gas and debris from the system to which fluid is supplied.
