Abstract: A champagne tower-type multi-stage throttle control valve includes a valve body, a valve cover, a throttle sleeve, and a valve core. A sleeve cavity of the throttle sleeve is shaped as a stepped hole with two or more layers. The valve core is shaped as a stepped shaft with two or more layers coaxial with the throttle sleeve. The number of shaft shoulders of the valve core is smaller than or equal to the number of hole shoulders of the sleeve cavity of the throttle sleeve, such that each set of shaft shoulders of the valve core in an axial direction can form a sealing surface fit with corresponding hole shoulders of the throttle sleeve. A flow channel groove is axially or obliquely formed on each of the hole shoulders of the throttle sleeve and/or the shaft shoulders of the valve core.

Abstract: Provided is a linear solenoid valve having at least one notch that opens on an end surface of the land of the spool on the drain chamber side and is formed on an outer peripheral surface of the land. In response to movement of the spool, a state is formed in which the end surface of the land on the drain chamber side is located inside the communication chamber and the output chamber and the drain chamber communicate with each other via the notch and the communication chamber, and a state is formed in which the end surface of the land on the drain chamber side is located inside the output chamber and the output chamber and the drain chamber communicate with each other via the communication chamber.

Abstract: An anti-surge recycle valve system for a natural gas line using a pipeline rotary control valve for controlling gas flow through the gas line and a valve controller having a surge-programmable feature including a threshold setpoint deviation limit, which is used to control first and second control valve loops. The first solenoid valve loop drives a rotary high-pressure piston actuator when the linear position sensor determines a setpoint deviation in gas flow below the threshold deviation, and the second solenoid valve loop drives the rotary high-pressure piston actuator when the linear position sensor determines a setpoint deviation in gas flow above the threshold deviation. The system provides ultra-rapid stroking speed in tandem with highly accurate and stable positioning.

Abstract: A control valve a body having a fluid inlet and a fluid outlet and a valve seat between the fluid inlet and the fluid outlet. A valve plug is positioned within the body and movable between a closed position, in which the valve plug sealingly engages the valve seat, and an open position, in which the valve plug is spaced away from the valve seat. A cage is disposed within the body adjacent the valve seat. The cage includes a cage wall having a throttling inlet and a throttling outlet, which are connected by a throttling passageway. The throttling passageway has a radial direction, an axial direction, and an angular direction between the throttling inlet and the throttling outlet. The passageway includes a plurality of vena contracta and a plurality of pressure recovery chambers, which form a plurality of pressure reducing stages.

Abstract: A valve trim includes a body having a plurality of parallel flow passages extending from a first end of the body to a second end of the body, opposite the first end. Each flow passage includes a throat and an expansion chamber and each throat is nested between the expansion chambers of directly adjacent flow passages.

Abstract: An example valve includes a valve body having a first port and a second port; a poppet movable within the valve body and comprising (i) a conical surface, (ii) an exterior cylindrical surface, and (iii) an annular groove; and a seal disposed in the annular groove of the poppet, wherein the poppet is movable to a partially-unseated position in which the poppet moves to form a flow area allowing fluid flow from the first port to the second port, wherein the exterior cylindrical surface of the poppet forms a flow restriction with the interior surface of the valve body downstream from the flow area, wherein the conical surface is configured to direct fluid toward the interior surface of the valve body, away from the seal, and wherein the flow restriction generates back-pressure around the seal to reduce velocity of fluid around the seal.

Abstract: Fluid damped check valves are described herein. A representative check valve includes a piston assembly movably positioned within a housing. The housing can include a flow chamber, a damping chamber containing a damping fluid, and a leak chamber fluidly coupled between the flow chamber and the damping chamber. The piston assembly can include a poppet positioned in the flow chamber, and a flange positioned in the damping chamber. In operation, the piston assembly is movable between (i) a closed position in which the poppet sealingly engages the housing to at least inhibit fluid flow through the flow chamber and (ii) an open position in which the poppet disengages from the housing and permits fluid flow through the flow chamber. When the piston assembly moves between the open and closed positions, the flange moves through the damping fluid in the damping chamber to slow the movement of the poppet.

Abstract: A valve comprises a flap, a tubular valve body defining an exhaust gas flow passage, and a device to guide the flap relative to the valve body to allow the flap to pivot relative to the valve body around a pivot axis between a closing position and a freed position of the exhaust gas flow passage. The flap has two large faces substantially parallel to one another and connected to one another by an edge of the flap. The guide device comprises a pin, a distal, end and a base. The valve also comprises a stabilizing member secured to the flap.
