A modular valve assembly includes a bonnetless main core, a first releasable connection, and a second releasable connection. A first inlet end connection includes a first inlet end flow passage. The first inlet end flow passage includes a curved portion that changes a direction of the first inlet end flow passage between 30 and 120 degrees. A second inlet end connection includes a second inlet end flow passage. The second inlet end connection passage is substantially straight. A first outlet end connection includes a first outlet end flow passage. The first outlet end flow passage includes an angled portion. A second outlet end connection passage includes a second outlet end flow passage. The first and second inlet end connections and the first and second outlet end connections are rapidly reconfigurable to form a variety of valve configurations.

Modular valve assembly

An anti-cavitation cage for a valve assembly. The anti-cavitation cage includes a body having a plurality of slots, a first end, and a second end. At least one slot of the plurality of slots includes an inside surface having a lattice structure. The lattice structure is one of uniform in grade through the at least one slot or a graded type of lattice structure varying in density from a first portion to a second portion. The anti-cavitation cage having these features is a single component.

A high flow/low flow valve includes a valve body having a fluid inlet and a fluid outlet connected to one another by a fluid passageway. A valve seat is disposed in the fluid passageway. A low flow valve plug is disposed in the fluid passageway proximate valve seat, the low flow valve plug cooperating with the valve seat to control fluid flow through the valve seat. A high flow valve plug is disposed in the fluid passageway proximate valve seat, the high flow valve plug cooperating with the valve seat to control fluid flow through the valve seat. A low flow actuator is operatively connected to the low flow valve plug and a high flow actuator operatively connected to the high flow valve plug.

Fluid valves with an anti-stagnation trim guide are disclosed herein. An example valve includes a valve body including a fluid inlet, a fluid outlet, and a fluid passageway extending between the fluid inlet and the fluid outlet, a plug disposed in the fluid passageway, and a trim guide positioned between the plug and the valve body, the trim guide including at least one balance passageway, the balance passageway to guide trapped process fluid to enter or exit an area between the plug and a bonnet of the valve during movement of the plug.

Fluid valves with an anti-stagnation trim guide

A fluid valve includes a valve body having a fluid inlet and a fluid outlet. A fluid passageway connects the fluid inlet and the fluid outlet. A trim assembly is located within the fluid passageway, the trim assembly controlling fluid flow through the fluid passageway. The trim assembly includes valve plug having an integrated staged pressure recovery.

A modular valve assembly can include a core spool module and a plurality of end connection modules. The end connection modules can be configured to be secured to the core spool module at one or more of a core inlet or a core outlet of the core spool module to provide one or more respective, different flow configurations for the modular valve assembly. The core spool module can include a bonnet portion that is integrally formed with the core inlet and the core outlet and a seat ring configured to provide a seal against flow of process fluid through the modular valve assembly.

A balanced trim pressure regulator includes a valve body having a fluid inlet and a fluid outlet connected by a fluid passageway. An orifice is disposed between the fluid inlet and the fluid outlet. A valve seat is disposed within the fluid passageway. A movable valve plug is disposed within the fluid passageway, the movable valve plug interacting with the valve seat to selectively open or close the fluid passageway. A cage is disposed in the fluid passageway, the cage surrounding the valve plug, and the cage including at least one a balancing passage that fluidly connects the fluid passageway with a balancing chamber.
