Quadax

Triple-offset butterfly valves for severe-service shutoff — engineered for steam, hydrocarbons, and the high-cycle applications that destroy resilient-seated butterflies.

About the Manufacturer

The Severe-Service Butterfly Valve, Engineered Right.

Quadax specializes in triple-offset butterfly valves (TOV) — a design that combines the compact footprint of a butterfly with the bubble-tight, metal-to-metal sealing performance of a gate or globe valve. The triple-offset geometry eliminates seal-disc rubbing and delivers zero-leakage shutoff through tens of thousands of cycles, even at high pressure and temperature.

Where resilient-seated butterflies fail in steam, hydrocarbon, or high-cycle service, Quadax TOVs deliver. Available in sizes from 3" through 60"+ and pressure classes from ANSI 150 to 2500, in carbon steel, stainless, duplex, and exotic alloy bodies for the toughest service.

"Triple-offset geometry means metal-seated, bubble-tight, fire-safe shutoff — without the wear that destroys resilient-seated butterflies."

Miller Valve has partnered with Quadax to serve customers across chemical, oil & gas, marine, and power generation. Engineering support, sizing assistance, and material selection for the specific service conditions your spec demands — backed by a stocking distributor in Birmingham.
