Abstract: Valve for fluid and gaseous media, more particularly for regulating the pressure in pipelines, containing a housing of at least one upper and lower part, a pressure adjustment unit, wherein the pressure adjustment unit comprises a spindle, a spring plate, a spring holder and at least one spring, a cartridge, wherein the cartridge forms a function unit by means of which the function of the valve is defined, wherein the cartridge preferably contains an interior housing, a fastening means, a poppet and a diaphragm, wherein the diaphragm serves for dividing the housing into a medium-free and a medium-flowing area, wherein the cartridge is pre-fitted as a function unit and is disposed replaceably as a complete unit in the housing.

Abstract: Valve bodies having integral boost reducing capability are described herein. An example fluid regulator includes a body having a main passageway defining an orifice to fluidly couple an inlet and an outlet where the main passageway defines an inlet volume boundary between the inlet and the orifice and an outlet volume boundary between the orifice and the outlet. A portion of the outlet volume boundary includes an inner wall adjacent the orifice. A valve plug is disposed within the second portion of the passageway such that the inner wall substantially surrounds an outer surface of the valve plug to substantially restrict fluid flow between the inner wall and the outer surface of the valve plug and toward the throat. The valve body having a secondary fluid passage within the outlet volume boundary to increase fluid flow toward the throat of the valve body when a fluid flows across the orifice.

Abstract: A fluid regulating device includes a regulator valve having an inlet, an outlet, and a valve port disposed between the inlet and the outlet. An actuator is coupled to the regulator valve and includes a valve disc that displaces along a longitudinal axis to open and close the fluid regulating device. The valve disc includes a sealing surface disposed adjacent to an outer radial end of the valve disc, and the sealing surface is adapted to sealingly engage the valve port in the closed position. The valve disc also includes an intermediate surface disposed inward of the sealing surface, and a groove is formed in the intermediate surface. The groove extends along a groove axis extending along the intermediate surface normal to the longitudinal axis, and the groove axis is at least partially curved when viewed along the longitudinal axis.

Abstract: A bellowphragm actuated fluid control swing valve includes: a fluid-tight body having an inlet for the fluid, a seat around the inlet, an outlet for the fluid, and a hinge, the body conducting the fluid from the inlet to the outlet; a fluid-tight chamber adapted to be pressurized with the fluid, the chamber generally enclosed by the body; a first surface of the chamber, foldably pleated so as to extend in response to the chamber being pressurized; second surface of the chamber, rotatably attached to the hinge, so that, when the first surface extends, the second surface rotates about the hinge; a disc on the second surface of the chamber that mates with the seat; and a generally non-folding cover attached to the first surface of the chamber so that the cover and first surface cooperate to form the chamber and make the chamber fluid-tight.

Abstract: Disclosed herein is an over-flow shutoff valve for a liquefied petroleum gas container The overflow shutoff valve includes: a gas inlet mounted at the gas container; a safety valve protrudingly formed at one side of the upper portion of the gas inlet for discharging the internal pressure of the gas container when the internal pressure is rapidly increased; a gas outlet protrudingly formed at the other side of the upper portion of the gas inlet for supplying gas to a gas appliance; a valve handle for vertically controlling a valve stem mounted on a controlling part protruding from the upper portion of the gas inlet; a gas inflow and outflow hole located between the gas inlet and the controlling part for allowing inflow and outflow of the gas; a cylinder fit into the inner circumference of the gas inlet; and a ball positioned inside the cylinder, the cylinder and the ball being adapted to normally discharge the gas contained in the gas container and regulate a gas flow to prevent an excessive outflow of the gas

Abstract: An excess pressure release is provided which at injector effect during inflation of an air cushion ensures an under-pressure in a part (23) of a valve chamber. By activating a piston (19), the underpressure retains the excess pressure release in its open position against the force of a spring (11), until a desired counter pressure from the filled air cushion stops the injector effect, whereby the excess pressure release is closed. As a result the air cushion may be inflated at a comparative high pressure and thus in a fast manner. The inflation is stopped automatically and securely, when the desired pressure has been reached in the air cushion.
