Ferrea Competition Plus Super Alloy Valve are Ferrea's Top of the Line Valve with all of the features, and is made from best quality material available. They are designed to withstand high rpm and high spring pressure at a fair price for a top of the line valve. Ferrea uses a 2 step slow forging technique applied to special alloys to create these Valve. They are heat treated and stress relieved with a swirl polished head.

Ferrea Competition Plus Valve have built a reputation as the industry's most reliable extreme duty valve. To manufacture the Valve 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 the material structure. The Valve are then heat-treated and stress-relieved over a 48-hour period, which is the crucial base of our molecular integrity. These Valve feature avionics-quality hard chrome along with a specially applied hard tip.
