A mixing valve includes a housing having, arranged therein: a first flow duct having a first flap mounted rotatably in the first flow duct and configured to influence the throughflow cross section of the first flow duct, and a second flow duct, the second flow duct issuing into the first flow duct, and having a second flap mounted rotatably in the second flow duct and configured to influence the throughflow cross section of the second flow duct. The first flow duct has, downstream of the issue of the second flow duct, as seen in the flow direction, a region with at least two cross-sectional widenings, and at least one stationary guide element, projecting into the first flow duct, is arranged in the region with the at least two cross-sectional widenings.

A shower jet device, includes a spray needle arranged in a spray nozzle; a cold water inflow space and a cold water jet outlet formed between the spray nozzle and the spray needle; a hot water inflow space formed between the spray nozzle and a valve body; wherein a cold water inlet respectively in communication with a cold water opening and the cold water inflow space; and a hot water inlet is respectively in communication with a hot water opening and the hot water space.

A system for supplying fuel includes a fuel manifold, a water manifold, and a fluid junction between the fuel manifold and the water manifold. A turbulator downstream from the fluid junction receives a fluid flow from the fluid junction. A method for supplying fuel includes flowing fuel through a fuel manifold, flowing water through a water manifold, and combining a portion of the water from the water manifold with the fuel from the fuel manifold to create emulsion fuel. The method further includes flowing the emulsion fuel through a turbulator.

A testing cap for a valve body includes a base configured to releasably attach to the valve body and to cover an opening in the valve body. The opening is configured to receive a valve cartridge and the base covers the opening in place of the valve cartridge. The testing cap includes a structure extending from the base. The structure is configured to be oriented relative to the valve body in a first orientation and a second orientation. The structure allows fluid to enter the valve body through an inlet port in the valve body and exit the valve body through an outlet port in the valve body when the structure is oriented in the first orientation. The structure covers at least one of the inlet port and the outlet port when the structure is oriented in the second orientation, thereby preventing fluid flow through the valve body.

Systems and methods include providing an aircraft with a direct drive dual-concentric valve (D3V) having a body, an outer secondary spool coaxially located within a bore of the body and linearly displaceable relative to the body, an inner primary spool coaxially located within a bore of the secondary spool and linearly displaceable relative to the secondary spool and the body. A plurality of piezo stacks is coupled to a first end of the primary spool, and applying a voltage to at least one of the piezo stacks causes an output stroke of the plurality of the piezo strokes for displacing the primary spool. The secondary spool is displaced together with the primary spool relative to the body if displacement of the primary spool relative to the secondary spool cannot occur.

A fluid control valve including a body, a first diverter, and a second diverter. The body includes an inlet that receives a supply of fluid, and first, second and third chambers. The first diverter is movable between first and second positions. When the first diverter is in the second position, the first chamber is fluidly connected to the inlet and the second chamber is fluidly disconnected from the inlet. When the first diverter is in the first position, the second chamber is fluidly connected to the inlet and the first chamber is fluidly disconnected from the inlet. The second diverter is movable between first and second positions. When the second diverter is in the second position, the third chamber is fluidly connected to the second chamber. When the second diverter is in the first position, the third chamber is fluidly disconnected from the second chamber.

A valve control is configured for use with control valves and other flow controls. The valve control leverages a simplified structure to avoid problems with manufacture and reduce costs. This structure includes a support unit that compresses parts of a valve housing together. Inside of the valve housing, the structure incorporates diaphragms that cause a pair of balanced valves to move in response to changes in pressure of fluid in a conduit. For industrial application, the valve control finds use to maintain pressure of natural gas in pipelines downstream from a control valve.

A solenoid valve system includes a valve body defining porting for a fluid flow through the valve body, and first and second solenoid valve components attached oppositely to the valve body. Each valve component includes an electromagnetically driven armature with a poppet that moves between a closed position and an open position. The porting defined by the valve body includes first side porting, second side porting, and common porting in fluid communication with an internal common chamber defined by the valve body. When a respective poppet is in the closed position, flow of fluid is blocked between the respective side porting and the common porting, and when the respective poppet is in the open position the poppet permits a flow of fluid between the respective side porting and the common porting through the common chamber.
