Patent number: 11643798Abstract: The system includes a fluid valve with a modular and/or replaceable fluid control assembly that requires maintenance over a product life of the fluid valve. The modular and/or replaceable fluid control assembly includes at least one portion including a setting or presetting configured and arranged to control fluid flow behavior in the fluid valve. The setting or presetting is useable to control fluid flow in the modular and/or replaceable fluid control assembly after an upgrade or replacement of at least a portion of the modular and/or replaceable fluid control assembly. Further, the setting or presetting enables the modular and/or replaceable fluid control assembly to retain the fluid flow behavior following one or more upgrades or replacements of one or more portions of the modular and/or replaceable fluid control assembly.Type: GrantFiled: May 27, 2021Date of Patent: May 9, 2023Assignee: FLUIDMASTER, INC.Inventors: Tuan Van Le, Joseph Unkyung Han, Salvador Pena
