MACH 1 Plug Valve ASME 300

The Mach 1 is the next generation of plug valve from Durco. The valve utilises a pair of PFA encapsulated taper seat inserts to replace the traditional PTFE sleeve used in the G4 series. The valve has many unique features allowing it to outperform comparable plug valves.

  • Lower turning torque – Reduced actuation costs
  • High working temperature performance up to 274° C
  • Easy seat replacement with minimal tools
  • ISO 5211 actuator mounting pad

The valve is available in a wide range of alloys to suit the process from carbon steel up to Zirconium / Hastelloy etc. Like all Durco plug valves the plug and be reseated whilst the valve stays inline. Whilst a live loaded reverse lip PFA diaphragm provides secondary stem sealing to keep emissions to a minimum.
The Mach 1 is available in sizes 1”NB up to 6”NB in class 150, class 300 and class 600 (derated) designs.
