An improved one-piece cage and an improved insert and their assembly create a zero-restriction fluid flow ball check valve. The improved insert for ball and seat valve comprises external screw threads on the base of the insert and have circumferentially spaced ribs extending upwards and converging towards the longitudinal axis of the insert, forming a hemi-spherical ball stop and arched side openings. The inside diameter of the insert bore is substantially equal to the ball valve diameter preventing the ball from rattling when positioned in the improved insert's passageway during the fluid flow. The outside diameter of the ribs is less than the inside diameter of the improved one-piece cage cavity producing a zero-restriction fluid flow ball check valve in comparison to the volumetric fluid flow through the annular seat. The improved cage that receives the improved insert is a one piece in construction and has internal threads that correspond to the external threads on the improved insert. The insert is assembled inside the cage using a screw thread connection and simultaneously forming a fluid seal between the insert and the cage.

A cage assembly for a valve includes a hollow first member having a first end for operably connecting to a valve body and an opposed second end for receiving a hollow second member. The assembly includes the second member having a third end for receiving a hollow third member, the second member including first openings formed through a sidewall, and the third member having a fourth end for operably connecting to the valve body. The assembly includes when assembled inside the valve body, the first member, the second member and the third member forming an aligned second opening therethrough, the second opening having a uniform cross section, for slidably receiving a valve closure element for controlling a flow of fluid through the first openings during operation of the valve.

A ball valve cage insert that includes: (1) a first section including an inlet ring having a radial wall thickness varies along the longitudinal axis of the cage; (2) a second section including side ribs that define a plurality of side openings, where the width of each opening varies from a first width at a first radial distance from the longitudinal axis to a second width at a second radial distance and (3) a third section including closure ribs extending from a first point at a first radial distance from the longitudinal axis to a second point where, as measured at a given radial distance from the longitudinal axis, the width of each closure rib varies from a first circumferential width at a first point on the longitudinal axis to a second width at a second point on the longitudinal axis.

A valve device includes a valve socket with a valve seat having internal radius, a valve disposed in the valve socket, and a first flow channel. The valve includes a valve housing, an inlet opening, a flow opening, and a stop. The valve housing includes a first housing portion sitting in the valve seat, and a second housing portion adjoining the first housing portion. The inlet opening is formed opposite the first housing portion and the flow opening is formed on the second housing portion. The stop sits on the valve housing at the inlet opening and radially protrudes beyond the valve housing. The stop includes a radial stop dimension greater than the valve seat internal radius, the radial stop dimension being a smallest radial distance between the valve axis and an area of the stop farthest from the valve axis. The first flow channel leads to the inlet opening.

A high flow high pressure hydraulic solenoid valve (26) includes a proportional 5 solenoid (56) and a valve body (30) operatively associated with the solenoid (56). The valve body (30) has a valve bore (32) and at least two fluid ports (38, 40) for fluid communication with the valve bore (32), wherein one of the at least two fluid ports (38, 40) includes an undercut (38b, 40b). The high flow high pressure hydraulic solenoid valve (26) also includes a valve member (42) 10 axially and slidingly disposed within the valve bore (32). The valve member (42) has a plurality of valve elements (44) spaced axially along the valve member (42). At least one of the valve elements (44) has a metering face (76a, 76c) acting with the undercut (38b, 40b). The one of the at least two fluid ports (38, 40) has two openings (82) located approximately one hundred eighty (180) degrees from each other in the valve body (30) and the valve member (42) has a control 15 module port (49a) configured to be ninety degrees from the at least one fluid port to balance pressure on the valve member (42) during high flow conditions.

A valve trim that is configured to abate noise in a control valve. These configurations may include a cage with a flow path that has interior and exterior openings. The cage may also have a bore to receive a closure member or plug. This plug can travel longitudinally to change parameters of flow through the control valve. In one implementation, the exhausts of flow paths with adjacent inlets are offset or spaced from another. In one implementation, the exterior openings vertically offset. However, other designs may adopt combinations of radial, helical, or angular offsets as well. This feature can prevent mixing of flow from jets that are in the same inlet plane. This feature, in turn, can reduce jet-to-jet interactions that may abate noise. Use of additive manufacturing may be useful (or even necessary) to create these parts within certain design envelopes because these techniques can create the unique flow geometry within a unitary or monolithic body. In this way, the valve trim of the present disclosure can maintain, or even reduce, costs of the control valve, while at the same time it can simply the overall construction of the valve device.

A valve assembly has a housing and a poppet-carrying portion. The housing includes an inlet port, an outlet port, an opening, and a assembly portion including helical grooves. The poppet-carrying portion is configured to be inserted through the opening and engage with the assembly portion. The poppet-carrying portion comprises a poppet head, a closure including protruding arms, convolutions, and a stopping portion. The convolutions extend between the poppet head and the closure and provide compliance such that the poppet head is movable relative to the closure. The stopping portion extends from the closure toward the poppet head and is spaced apart from the poppet head by a maximum compression distance. At a first fluid pressure, the protruding arms engage with the helical grooves, and the poppet head is positioned in a pre-load position that prevents the fluid from discharging through the outlet port.
