In embodiments, a gate valve includes a valve body including a flow passage from a first opening to a second opening, and a gate channel having a first end intersecting the flow passage and a second end delineated by a third opening. A valve cover fits over the third opening. A cap fits over a valve cover opening. In embodiments, a valve cover includes a body with a second sealing surface protruding from a first sealing surface, both around an opening of the body. A cap has a third sealing surface to mate with the first sealing surface, and a fourth sealing surface congruent to the second sealing surface. In embodiments, a valve cover cap includes a body with a first sealing surface on an end of a wall. Pin flanges each have a pin hole having a pin hole axis oriented perpendicular to a center axis of the wall.

A multi-passage coolant valve may include an outer housing including an outer body formed with a first outer inlet, a second outer inlet, a first outer outlet, and a second outer outlet, and an auxiliary body formed with a third outer outlet, and an inner housing rotatably provided in the outer housing. As the inner housing rotates by a predetermined angle, the first outer inlet and the first outer outlet are fluidly communicated with each other, the first outer inlet and the second outer outlet communicate with each other, and the second outer inlet and the third outer outlet communicate with each other.

An assembly having at least two chambers (1, 2) and at least one transfer valve (3), wherein: a valve housing interior (9) of the transfer valve (3) is separated from each the chamber interiors (4, 5) of the chambers (1, 2) by respective partitions (12, 13) and a transfer opening (14, 15) for the feeding through of objects and/or fluids is formed in each of the partitions (12, 13) and in addition to the transfer opening (14, 15) in question an additional opening (16, 17) is arranged in each of the partitions (12, 13). The additional openings (16, 17) can be closed by respective switching valves (18, 19) of the assembly and, in an open state of the respective switching valves (18, 19), directly fluidically connect the valve housing interior (9) to the respective chamber interiors (4, 5) adjoining the respective partitions (12, 13).

A globe valve, having a body through which a fluid circulation duct passes, the latter delimiting a fluid path with an inlet and an outlet, and a shutoff member housed inside a branch generally perpendicular to the body, this shutoff member being movable between a first end position, in which it shuts off the duct, and a second end position, in which it does not shut off the duct, wherein the duct has, on either side of the region of action of the shutoff member, a generally circular liquid circulation section, which is connected continuously, at least in the region of action of the shutoff member, to a section that is longer than it is wide, the body (2) not having an element that protrudes towards the inside of the duct.

The fluid channel structure includes a base and a connector. The base includes a first side surface defining at least three first openings, and a second side surface defining at least three second openings, each of the at least three first openings is communicated to one corresponding second opening to form a first inlet channel, a second inlet channel, and an outlet channel, inner surfaces of the first inlet channel, the second inlet channel, and the outlet channel are provided with threaded connecting elements. The at least three through holes are in one-to-one correspondence with the at least three first openings and communicated to corresponding second openings. The present disclosure further provides a valve core assembly and a tap.

A flow control device includes a valve body having an inlet, an outlet, and a flow path connecting the inlet and the outlet. A flow vane is coupled to the valve body and disposed in the flow path to divide a flow of fluid through the valve body. The flow vane has a first surface, a second surface, and a corrugation formed on at least one of the first and second surfaces. A control element is disposed in the flow path and movable in the valve body between an open position and a closed position.

Rotary valve systems with integrated sensors are described that facilitate stabilizing electrical connection from a valve actuator. A valve system includes a rotary valve comprising one or more ports configured to receive one or more fluids. The valve system further includes an actuator attached to the rotary valve, wherein the actuator comprises a power connection fed from electronics associated with the actuator. The valve system further includes an actuator cap attached to the actuator, the actuator cap configured to allow the power connection to pass through, wherein the actuator cap comprises one or more apertures, a valve collar with an integrated press-on connector configured to be attached to the actuator cap, wherein the valve collar comprises an electronic feedthrough passage for the power connection, a retainer portion comprising one or more retainer pins, wherein the one or more retainer pins are configured to mate with the one or more apertures on the actuator cap, the retainer portion configured to allow electrical connection between the power connector and a sensor connector when the one or more retainer pins fit within the one or more apertures on the actuator cap, and a sensor housing adjacent to the rotary valve and configured to support one or more sensors disposed with respect to one or more fluid lines coupled to the one or more ports of the rotary valve, the sensor connector configured to transmit signals from the one or more sensors to the actuator.

An object is to provide a fluid handling device which can be easily manufactured and which makes it possible for a valve to be easily opened and closed with a small force. A fluid handling device for achieving the above object includes a first region; a second region; and a valve disposed between the first region and the second region, in which the valve includes: a groove-shaped valve seat disposed in a board, and a flexible layer covering the groove-shaped valve seat, and a surface of the flexible layer facing the groove-shaped valve seat is a flat surface, a protrusion is disposed on a side of the flexible layer opposite to the groove-shaped valve seat and at a position corresponding to the groove-shaped valve seat.
