A valve cage for guiding an actuator, such as a stroke piston, may be used in a control valve for adjusting a process fluid flow (e.g., a water flow) in a process plant (e.g., a food processing plant, a brewery, etc.) The control valve may include a sensor for detecting a chemical and/or biological property of the process fluid, and at least one analyzer for the process fluid that is arranged on the valve cage such that the analyzer can interact with process fluid.

A fluid pump may include a power end, a fluid end having a cartridge bore, and a valve cartridge configured for insertion into, and removal from, the cartridge bore as a unit. The valve cartridge may include a cartridge body having a fluid inlet and a fluid outlet, a first valve assembly configured to control fluid flow through the fluid inlet, and a second valve assembly configured to control fluid flow through the fluid outlet.

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 check valve is arranged in a flow path through which hydraulic fluid flows. The check valve includes: a cap fixed in the flow path; a plug seated on a seat surface provided in the flow path; a first extension provided in the cap and extending from the cap toward the plug; a second extension provided in the plug, extending from the plug toward the cap, and guided by the first extension; and a spring interposed between the cap and the plug to bias the plug toward the seat surface. The check valve further includes a retainer attached to the cap, extending from the cap toward the plug, and locked to the second extension.

A valve cartridge assembly may include a valve cartridge housing defining a suction chamber that is open at a first end of the valve cartridge housing and one or more first passageways through the valve cartridge housing that lead into the suction chamber, and a discharge chamber that is open at a second end of the valve cartridge housing and one or more second passageways through the valve cartridge housing that lead into the discharge chamber. The discharge chamber may be fluidly isolated from the suction chamber through the valve cartridge housing. The valve cartridge assembly may include a suction valve assembly, including a suction valve that seals the suction chamber, that is configured to control flow through the suction chamber. The valve cartridge assembly may include a discharge valve assembly, including a discharge valve that seals the discharge chamber, that is configured to control flow through the discharge chamber.
