A combined ball valve for compressor bleed air modulation is provided. The combined ball valve includes a housing defining an inlet, and first and second outlets. A metering element is positioned within the housing and within a flow path extending from the inlet to the first and second outlets. The metering element includes first and second flow ports and is rotatable within the housing to modulate compressor bleed air from the inlet to neither, one, or both of the first and second outlets. The combined ball valve utilizes high temperature materials in a relatively lightweight package.

The present disclosure discloses an auto-switching tee joint, including a transitional tube, a first inlet tube, a second inlet tube and an outlet tube. The first inlet tube and the second inlet tube are disposed at two ends of the transitional tube, and the outlet tube is connected at a side wall of the transitional tube. In the transitional tube, there is provided with a switching ball which is movable freely. Both the first inlet tube and the second inlet tube have a bell-mouth which faces the transitional tube. The switching ball has a diameter larger than a minimum inner diameter of the bell-mouth and larger than an inner diameter of the outlet tube. The present disclosure further provides a device for washing and drying clamps which adopts the above auto-switching tee joint and can accomplish the washing and drying of clamps, save costs and improve working efficiency.

A rotary valve is provided including a housing with an inner chamber having a first inlet, a first outlet, a second inlet, and a second outlet. A valve body is rotatably positioned in the housing. The valve body includes at least one isolated fluid pathway that, depending upon a rotational position of the valve body, provides at least one of a direct connection of one or more of the inlets to one or more of the outlets, or permits flow from at least an other one of the inlets or the outlets that are not in the direct connection created by the at least one isolated fluid pathway into or from the inner chamber. At least one actuator controls the position of the valve body.

A new cement valve is disclosed for use in the production of an oil or gas well where hydraulic fracturing has been employed. In particular, the embodiments include a cement valve having a reclosable valve. When properly located, a first piston sleeve is hydraulically actuated to open the cement ports on the tool. After the cement has been pumped through the tool and the cement ports to a wellbore annulus, a blocking ball is dropped to stop flow through the tool. The tool is internally pressurized. The pressure overcomes shear pins to force downward movement of a ball housing inside the cement valve. This movement translates a travelling pin along a guide path, which rotates a ball valve inside the ball housing, releasing the blocking ball to open up the internal flow path through the cement valve at the same time the cement ports are closed.

A multifunctional expansion valve may include a second exit, and a chamber fluidically-communicating with the first entry, the second entry, the first exit, and the second exit, and a needle valve movably mounted in the chamber of the valve body along up and down directions, wherein the first entry and the first exit are selectively fluidically-communicated to each other and the second entry and the second exit are selectively fluidically-communicated to each other according to a position of the needle valve.

A heating installation or cooling installation mixing device has a valve housing (14) including a first flow path from a first connection (A-B) to a second connection (A), and a second flow path from the first connection (A-B) to a third connection (B). A movable valve element (24), arranged inside the valve housing (14) in the flow paths, is configured to vary a ratio of cross sections of the flow paths. A valve element drive (36) is arranged on the valve housing (14) and includes an internal control device (38) for movement control of the drive (36) and includes a first communication interface (44) for external control device (40) communication and a second communication interface (46). An internal sensor (48, 50) is arranged in or on the valve housing (14) and is connected to the first communication interface (44) for transmitting a sensor signal to the external control device (40).

A flow path switching valve is used in an engine water cooling system mounted on a mounting surface of an engine, and switches a flow path of a cooling water in the engine water cooling system. The engine water cooling system has a block jacket formed on a cylinder block and a head jacket formed on a cylinder head, connected to each other via a communication passage. The cooling water flowing in from an inlet of the block jacket flows into an inlet port of the flow path switching valve from an outlet of the head jacket via the communication passage. An inflow barrier plate is provided, which closes a part of a leak path side of the inlet port to suppress an inflow of the cooling water from the block jacket via a leak path made in the cylinder block and the cylinder head.

A fluid control device (100) having a housing (10) with at least one first port (16) and at least one second port (18, 20), wherein a valve body (30) is enclosed in the housing (10), the valve body (30) providing a fluid path (60) having a first path portion (62) proximal to the first port (16) and an opposing second path portion (64) in a distance from the first port (16) and proximal to the at least one second port (18, 20), the fluid path (60) being switchable between at least a first position (80) and at least a second position (82) in relation to the at least one second port (18, 20) by rotating the valve body (30) around the first main axis (22) of the at least one first port (16).
