A device (1) for controlling the flow of a fluid through a conduit (3) from an upstream side (8) to a downstream side (10). The device includes a housing (4) having one or more valve apertures (6) through which the flow of fluid is selectively controlled. A valve member (12) is mounted on the housing and arranged to move reciprocally to selectively open and close the one or more valve apertures. A seal (20) is arranged at or beyond a position the valve member reaches when the one or more valve apertures are all closed. The device also includes a resilient member (26) that acts to bias the seal towards the valve member.

A non-plugging, multi-stage valve trim and a fluid flow control device employing the same. The valve trim includes a unitary cage body extending along a longitudinal axis, and a valve plug movably disposed within the unitary cage body to control fluid flow through the unitary cage body. The unitary cage body includes an outer wall arranged to engage the valve body, an inner wall spaced radially inwardly of the outer wall, a cage inlet formed in the outer wall, a cage outlet formed in the outer wall, and a pressure reducing fluid flow passageway formed within the unitary cage body and extending between the cage inlet and the cage outlet.

The device includes one or more valve apertures (6) through which the flow of fluid is selectively controlled. A valve member (12) is arranged to move reciprocally to selectively open and close the one or more valve apertures. The device includes a stop (18) for arresting the travel of the valve member arranged at or beyond a position the valve member reaches when at least some of the one or more valve apertures are open. The valve member includes an end portion (13) arranged to come into contact with the stop when the valve member reaches or passes the position at which at least some of the one or more valve apertures are open and a body portion (9).

Fluid flow control devices comprise a body including a central aperture extending along a longitudinal axis therethrough and a plurality of channels extending from an outer sidewall of the body to an inner sidewall of the body. At least one first channel may intersect at least one other channel. Fluid flow control systems, methods of forming fluid flow control devices, and methods of flowing a fluid through a fluid flow control device are also disclosed.

A solenoid-operated valve assembly that reduces the jet flow of fluid or gas in an axially exiting valve. The valve assembly comprises a spool valve, a valve member housing, and a flow path. The spool valve comprises a fluid communication channel, a tail, and an inlet seat. The valve member housing comprises at least one inlet, at least one nozzle flow director, and at least one outlet. The flow path begins at the at least one inlet and exits at the at least one outlet. The at least one nozzle flow director is within the flow path. The spool valve moves axially within the valve member housing between a closed position and an open position. The inlet seat closes the at least one flow path at the inlet when the spool valve is in the closed position. A method of operation of the solenoid-operated valve assembly is also provided.

A fluidic control valve configured to control a flow of fluid through a conduit includes a piezostack actuator, a seal plate having a sealing face, an orifice plate including a plurality of orifices, and a suspension connected to the seal plate. The piezostack actuator is configured to displace the seal plate along a longitudinal axis of the conduit between a closed position, in which the sealing face engages the orifice plate, seals the orifices of the orifice plate and closes the valve, and an open position, in which the seal plate is displaced from the orifice plate to open the valve. The suspension is configured to flex and adjust an orientation of the sealing face relative to the orifice plate during movement of the seal plate from the open position to the closed position.

The high pressure valve (1) has a high pressure region (2) and a low pressure region (3) and a shut-off element (4). The shut-off element (4) is designed for closing and opening a fluid connection between the high pressure region (2) and the low pressure region (3) and to this end it can be moved in an axial direction (Z) between a closed closure position and an opened opening position. A seat gasket (9) is provided to form a seal in the closure position. The seat gasket (9) is a compression sealing seat gasket (9) which is affixed to the shut-off element (4) and is arranged in a recess provided in the shut-off element (4).
