A valve assembly including a valve body with an inlet port and an outlet port, a flow passage and a valve element disposed within the flow passage, an actuator and a lockout mechanism configured to maintain the position of the valve assembly in an opened position or a closed position. The lockout mechanism can include at least one screw.

Valve assembly and lockout mechanism

The present invention relates to a valve assembly that includes a retaining ring disposed within a cavity formed by adjoining a retainer and a disk member. The retaining ring can be disposed at a slant with respect to an inner surface of the cavity.

Seal, assembly, and retention method

Provided is a valve assembly system including a flowbody including a channel formed at an inner surface thereof, a butterfly plate disposed within the channel and rotatably mounted within the flowbody. The system also includes a pair of dual-sided pistons that receive differential pressure at an input side and an output side of the valve assembly system. A spring is controlled for biasing against at least one of the dual-sided pistons based on the differential pressure, and to rotate the butterfly plate to regulate the differential pressure and the valve assembly system to a predetermined output pressure.

Differential pressure regulating shut-off valve

An air pressure regulator includes a regulator body defining a hollow interior, an air inlet in communication with the hollow interior and configured to connect with a source of pressurized air, an air outlet fluidly coupled with the air inlet, and a valve stem positioned at the air inlet and configured to regulate the pressure of the pressurized air for the air outlet by way of movement of the valve stem relative to the air inlet.

Air pressure regulator

A gas/air mixer assembly provides a Venturi metering system that may draw fuel from a zero governor, mix it with air to form a homogenous gas/air mixture for delivery to an internal combustion engine. The gas/air mixer assembly may also accept fuel under pressure from a gas metering valve or fuel injector for delivery to an internal combustion engine. The mixer includes an air horn, the relative position of which in relation to a shaped restriction body governs the air flow into the engine intake manifold. The flange of the air horn is configured to redirect the flow of air without generating significant turbulence, and providing a maximum velocity perpendicular flow to the injection of fuel to be mixed therein. The relative position of the air horn to the shaped restriction body is determined based on the cubic capacity and speed of the engine with which it is used.
