Ferrea Competition Plus Valves have built a reputation as the industry's most reliable extreme duty valve.


  • To manufacture the valves we use special aerospace quality alloys, including the EV8-Z18, which provides high tensile strength.
  • An exclusive two-step slow forging process ensures proper grain flow and virtually eliminates any damage to thematerial structure.
  • The valves are then heat-treated and stress-relieved over a 48-hour period, which is the crucial base of our molecular integrity.
  • These valves feature avionics-quality hard chrome along with a specially applied hard tip.
