Abstract: A single handle mixing valve of the plate valve type where a single stem controls both the temperature and flow output from the valve. A control said characteristic plate having an opening is positioned over the stem and has at least one surface defining limits of stem movement. An actuating ring positioned within an exterior cover for the mixing valve has inwardly facing cam surfaces, which interact with the control plate to adjust either maximum temperature or maximum flow from the valve. The actuating ring has a tab extending to the outside of the exterior cover for convenient operator manipulation without the need for disassembly or the use of tools.

The oil housing is divided into two chambers, the float is provided in a first chamber, and a further float is provided in a second chamber. It is significant for the oil deaeration device that the diaphragm on one side is connected to the first chamber, that the diaphragm on its other side is connected to the second chamber, that a safety valve is provided in connection with the outlet, and that the safety valve communicates with the outlet in its open position.

Abstract: A valve body is provided with at one end with a threaded shank for hermetic coupling to a gas container. The valve body is further provided with a handwheel incorporating a gas status indicator device. That device includes a spring-loaded plunger having a head and a helical stem that is engaged in a cavity of a rotatable body so that an axial movement of the plunger, in opposition to a spring biasing force, results in a rotation of the rotatable body. A visible portion of the rotatable body is marked so as to provide an indication of the axial position of the plunger relative to the handwheel, to thereby indicate gas pressure.

Abstract: A control valve for regulating flow of fluids passing through the valve. The control valve includes a body with an inlet, an outlet and a passageway through which the fluid passes from the inlet to the outlet. The control valve also includes a displaceable column provided with an internal and concentric bolt, the displaceable column is actuated by an actuator, the actuator positioned in a chamber that is connected to the body, a valve closure attached to the displaceable column. The displaceable column moves between a most retracted position, in which the inlet is fluidically communicating with the outlet, and a most pulled out position, in which the valve closure sealingly blocks the passage of fluid through the control valve.

Abstract: A mixed water faucet includes a valve seat, a control valve, a flow control member, a handle, and a nozzle. Thus, the mixed water faucet has a simplified construction, thereby decreasing costs of fabrication. In addition, the mixed water is controlled exactly by operation of the handle, thereby facilitating a user controlling the water temperature. Further, the mixed water faucet has a self-flush function by provision of the self-flush handle.

Abstract: An internal blow out preventer is provided that includes a ball valve including a tubular assembly having a central passageway with upper and lower seats mounted therein. A ball is rotatably received between the upper and lower seats and includes an external surface and a central opening, wherein the central opening includes an undercut. A protective coating is applied to both the external surface and the undercut of the ball.

Abstract: A valve assembly that includes a valve body defining a fluid passage. First and second ends of the fluid passage define first and second ports for fluid flow. A spring and piston are located in the fluid passage. The piston has a travel length extending between first and second positions with a third position located therebetween. The spring biases the piston from the first toward the third position and is located outside the axial piston passage. The piston at least partially defines a first, second and at least one third opening. The first opening defines a variable constriction which increases in size as the piston moves from the first to third positions. The piston end wall defines the second opening and the piston sidewall defines the third openings. Movement of the piston from the third to second position exposes the third openings increasing the area of the second port.

Abstract: A large-scale system for storage and mixing of a solution comprising a plurality of ingredients not compatible for long-term storage in a pre-mixed formulation includes a storage tank that is divided into a plurality of compartments each of which is adapted to isolate and store a proportionate amount of ingredient, fluid conduits for withdrawing and conveying the ingredients from the compartments, valves for controlling the flow of ingredients and for preventing backflow, a manifold for continuous mixing and blending of the ingredients as they are withdrawn, a sump for holding a quantity of the mixed solution, a display to enable monitoring of system parameters and a discharge port to which conduits may be coupled for withdrawing the mixed solution from the system.

Abstract: An air inflation tube of a mini-size air pump is disclosed. The air inflation tube of the air pump has a dual direction air inflation capability, that is, inflation and deflation, and the pressure releasing and air pumping are done by the same tubular body to solve the problem of excessive tire pressure without removing the air inflation tube.

Abstract: A connector apparatus designed for use in a bioprocessing assembly, and a method for coupling a piece of bioprocessing equipment to a media source in a sterilized environment. The connector apparatus includes a coupler including an end and at least one outlet, and a connector valve connectable at a first end to a fluid source, the connector valve including a valve member, the valve member being partially disposed within the coupler. The connector apparatus further includes a flow passage being actuatable from a closed configuration to an open configuration when the coupler and the connector valve are engaged, as well as being actuatable from an open configuration to a closed configuration. A clip member attached to the coupler allows the valve member to be moved from the closed configuration to the open configuration, and from the open configuration to the closed configuration.

Abstract: In an apparatus for regulating the internal pressure of a closed system, a valve housing connected to a closed system, an intake valve connected to a valve housing for receiving a pressurized substance in one direction through the valve housing into the closed system, and a release valve connected to the valve housing for releasing excess pressure from the closed system. The release valve has a release valve aperture for releasing pressurized substance, a release valve block for selectively preventing the pressurized substance from escaping through the release valve aperture, and a release valve spring for retaining the release valve block in a closed position. When the constant internal pressure is increased, the release valve spring causes the release valve block to move from the closed position to an open position, thereby allowing excess pressurized substance to escape from the release valve aperture.

Abstract: A valve device includes a housing including a peripheral valve seat extended into a chamber, to separate the chamber into two separated spaces. A valve member includes an outer peripheral groove to receive a sealing ring for engaging with the peripheral valve seat of the housing, to make a seal between the valve member and the peripheral valve seat, and a casing is secured to the valve member. A spring member may bias the casing away from the peripheral valve seat, to force the sealing ring of the valve member against the peripheral valve seat, and to make a fluid tight seal between the valve member and the peripheral valve seat.

Abstract: A poppet-type check valve for controlling fluid flow, and including a valve housing having an interior and first and second ports therein communicating with the interior of the valve housing for permitting fluid flow from an upstream side to a downstream side thereof. At least one valve assembly is disposed within the interior of the valve housing for controlling the fluid flow therethrough. The valve assembly includes a valve seat positioned in the interior of the valve housing and a seal retainer positioned in the interior of the valve housing downstream from the valve seat and mounted on a stem. The seal retainer and the stem are axially moveable away from the valve seat in response to fluid flow in a downstream direction at a predetermined flow rate, and axially moveable towards and into sealing engagement with the valve seat in response to a downstream fluid flow at a flow rate less than the predetermined flow rate.
