Sleeved Plug Valves
Steel body with replaceable PTFE/PFA sleeve over the plug. Easy maintenance — replace the sleeve, not the whole valve. Sizes 1/2" through 12".
PFA and PTFE-lined plug valves — engineered for sulfuric acid, chlorine, hydrofluoric acid, and the corrosive process streams that destroy unlined valves.
FluoroSeal specializes in PFA and PTFE-lined plug valves — the workhorse design for the most corrosive chemical processes in industry. Sulfuric acid at every concentration. Hydrochloric, hydrofluoric, nitric. Sodium hydroxide. Wet chlorine. The kind of media that eats stainless and pits even Hastelloy.
What sets FluoroSeal apart is the combination of mechanical durability (steel body shells designed for industrial duty) with chemical inertness (PFA/PTFE liners that resist virtually every commercial chemical). Sleeved-plug designs allow easy in-line maintenance. Multi-port configurations available for divert and sampling service.
Miller Valve has partnered with FluoroSeal to serve customers in chemical processing, pulp & paper bleach plants, mining leach circuits, and steel mill pickling lines. Materials selection support, sealed-bearing options, and stocking inventory for the configurations chemical plants run every day.
Four product families covering sleeved, fully-lined, multi-port, and sampling configurations — for every aggressive chemical service.
Steel body with replaceable PTFE/PFA sleeve over the plug. Easy maintenance — replace the sleeve, not the whole valve. Sizes 1/2" through 12".
Body and plug fully lined with PFA or PTFE — no metal contact with the process media. For the most aggressive services.
Three-way and four-way plug valve configurations for divert, mixing, and sampling service. All with full chemical-resistant lining.
In-line sampling valves for hazardous and corrosive media. Closed-system designs for operator safety in chemical service.
