A flow control valve includes an inlet, an outlet, and defines a fluid flow path. A valve seat is disposed within a valve body, and a valve plug in the valve body is surrounded by a cage. An exterior surface of the valve plug includes a plurality of notch sets, each notch set spaced apart from an adjacent notch set along the longitudinal axis, and the cage is disposed within the valve body and arranged to retain the valve seat, with an interior of the cage including a plurality of annular recesses. The annular recesses are spaced apart along the longitudinal axis, and the cage includes a plurality of apertures forming a portion of the fluid flow path. The notch sets and the recesses are arranged to form a plurality of turns in the fluid flow path when the valve plug is shifted toward the open position.

Flow control devices for convector heaters are provided. Such devices may include a casing in the shape of a cylindrical tube having in a first portion thereof, facing in a mounted condition towards the intake conduit of a convector heater, a plurality of first openings and in a second portion thereof, facing in the mounted condition towards the opposite side of the intake conduit, a plurality of second openings, the casing being arranged to be mounted onto the ceiling (S) in such a manner that the first and second openings allow the inside of the casing to be placed into communication with a first space (A1) beneath the ceiling (S) and with a second space (A2) above the ceiling (S), respectively; a closure member in the shape of a cylindrical tube which is mounted within the casing and is axially slidable relative to the latter between a first position, in which it leaves the first openings open and closes the second openings, and a second position, in which it closes the first openings and leaves the second openings open; and actuation elements for controlling the axial sliding movement of the closure member relative to the casing between the first and second position.

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 device (1) for controlling the flow of fluid through a conduit from an upstream side (3) to a downstream side (5). The device includes a housing (4) with a wall (6) having valve apertures (8) through which the flow of fluid is selectively controlled. A valve member (10) is mounted on one side of the wall of the housing and is arranged to move reciprocally to selectively open and close the valve apertures. A removable insert (12) is mounted on the opposite side of the wall of the housing from the valve member. The removable insert is arranged to cover some of the valve apertures.

A cage for a control valve trim assembly includes a cage body having an opening at one end and a wall extending from the opening, a plurality of cage openings disposed in the wall, and a pressure relief mechanism disposed in the cage wall.

A method of controlling the flow of a fluid in a pipe system includes controlling a sleeve valve in the pipe system, the sleeve valve includes a valve body having an inner surface and an outer surface defining an inlet, an outlet, and a body cavity between the inlet and the outlet, a sleeve disposed at least partially within the body cavity, the sleeve including at least one opening fluidly connecting the inlet to the outlet, a gate proximate to the sleeve, and a drive assembly including a pair of drive lines, each drive line including a drive shaft, a first drive line of the pair of drive lines including a sync cam on the first drive line movably positioned between the front stop and the back stop, and moving the gate to uncover the at least one opening to allow fluid to flow from the inlet to the outlet.

A method of controlling the flow of a fluid in a pipe system includes controlling a valve in the pipe system, the valve including a valve body having an inlet, an outlet, and a body cavity, a gate moveable over a portion of the valve body at least partially between the inlet and the outlet, the gate including a cam stop, and a drive assembly, the drive assembly including a pair of drive lines, a first drive line of the pair of drive lines including a sync cam, the sync cam of the first drive line movably positioned on the drive shaft of the first drive line and positioned relative to the cam stop, moving the sync cam in a first direction to a front stop position; and moving the gate in the first direction to allow fluid to flow from the inlet to the outlet.
