Abstract: The present invention relates to an expansion valve intended to be arranged in a fluid passage between an upstream conduit and a downstream conduit, the expansion valve comprising: —a tubular valve body which is provided, in an upstream axial end section, with at least one upstream orifice intended to be in communication with the upstream conduit and, in a downstream axial end section, with at least one downstream orifice intended to be in communication with the downstream conduit, the downstream orifice and the upstream orifice being connected by a main channel, —a shut-off device which is movable between a closed position and an open position with respect to the downstream orifice. The shut-off device includes a slider which is mounted to slide axially on the downstream axial end section of the valve body.

Abstract: An electromagnetic rising stem valve includes a stopper configured to block flow of fluid within a pipe. The stopper is connected to a shaft configured to be rotated via an electromagnetic force generated between magnets attached to the outside of the shaft and magnets surrounding an outside surface of a section of the valve. The rising stem valve is further able to include a second shaft which is directly rotated by the electromagnetic force, to open, closed, and one or more semi-open positions, and which is coupled to the shaft connected to the stopper via gearing. Advantageously, the one or more shafts and any gearing is entirely contained within a gear housing, with the electromagnetic force being generated by interaction with magnets outside the housing entirely, preventing unwanted leakage of fluid from the pipe into the environment.

Abstract: The Disclosed is a solenoid valve, in which a rod is moved by a plunger that comes into contact with and separates from a stator by electromagnetic force, causing a valve body that opens and closes a valve to move reciprocally. The valve is configured such that a first space and a second space are formed at respective sides of the plunger in the movement direction thereof, a through-hole is formed in the plunger so as to be concentric with a center axis, the rod is arranged in the first space, and a communication passage is formed between an inner surface of the plunger and an outer surface of the rod and communicates with the first space S1 and the second space.

Abstract: A reversible electromagnetic valve is provided, which includes a valve seat having a valve port, a slider slidably connected to the valve seat, and a driving member. The driving member can drive the slider to move in contact with the valve seat to use a sealing surface of the slider to selectively block the valve port. The sealing surface of the slider has a sealing point; the sealing point is provided corresponding to a limit position of an edge of the valve port of the valve seat, such that when the slider drives the sealing point to cross the valve port, the sealing surface of the slider can block the valve port; and under action of a pressure difference, a position where the sealing point of the slider is located is not lower than a plane where the edge of the valve port is located.

Abstract: The present invention relates to a hydraulic built-in valve (100) for a valve block (10), comprising a sleeve (110) that is introducible into the valve block, and a closing element (130). The sleeve comprises a first end region (111) which is connectable to a control cover. The sleeve comprises a second end region (112) which is at the opposite end from the first end region and is introducible into the control cover, wherein the second end region has, in a frontal end, a frontal opening (114), and the sleeve forms, between the first end region and the second end region, a shell (117), having an outer side and an inner side, and the shell of the sleeve has a multiplicity of shell apertures (119) separated by shell webs (118). The closing element is arranged movably in the sleeve, wherein the closing element is movable between a first position and a second position, and wherein, in the first position, a fluidic connection between the frontal opening and the shell apertures is opened up, and, in the second position, a fluidic connection between the frontal opening and the shell apertures is closed off, wherein the shell apertures extend along the shell in the direction from the first end region to the second end region and form an aperture height, and the shell apertures have a height/width ratio of at least 3:1.
