Super Flo vs. Flo

This Super-Flo valves (often referred to as under-cut or Neck-down), that actually reduces the stem diameter in the port area. This increases flow over “straight” stem diameter (Flo valves) considerably without adverse effect on reliability....

Valve Materials

Proper material choice for the application is crucial to the valve performance and reliability. The extreme change of temperature to a valve in the combustion chamber area (in excess of 1600ºF) and in the intake manifold area (up to -25ºF), can cause “thermal fatigue”. The material’s ability to resist these drastic thermal variations is crucial to the valve life. This is why Ferrea is constantly testing and evaluating new materials and processes to provide the highest level of “fatigue resistance” in the industry....

Competition Plus Valves

Ferrea Competition Plus Valves have built a reputation as the industry's most reliable extreme duty valve. We, at Ferrea, are dedicated to providing the absolute best product on the market.

Our extensive R & D programs provide technological gains, which are implemented in each of our competition plus valves. They are engineered for high RPM, high horsepower racing engines, and are chosen by many top NASCAR, Drag, Oval & Sprint Car - racing teams....

Ferrea Lightweight Lifters

Ferrea Lightweight Pro Solid Lifter is precisely that weighing in at just 59 grams. Forged from super clean Tool Steel alloy ensures greater molecular density, increased resistance strength and durability to higher levels of compressive stresses....

Hollow Stem Valves

One important factor to take into consideration to increase the engine’s rpm’s, is the valve train weight. Of course,being the valve amain component, the design has to be perfected to accomplish the weight reduction to allow higher rpm’s. Ferrea’s latest contribution to this area is the introduction of its Lightweight Hollow Stem Valve. We develop a manufacturing process that gun drill and micro polish the stem to achieve a valve reduction in weight of 20 percent compared to a conventional stainless steel solid stem valve....

5000 Series Valves

The 5000 Series Valves have become the alternative for performance engine builders that use our competitors “street” or “performance valve”. These valves are machined in our CNC centers allowing tight tolerances and cost effective design....

6000 Series Valves

The 6000 Series Competition Valves are designed to provide excellent reliability in an environment of high spring pressures and roller cams, at a budget price. They have higher fatigue resistance and tensile strengths than our competitor’s best offerings....

Super Alloy Valves

The super alloy valves represent the highest level of sophistication in valve technology. These valves are designed to handle the extreme heat requirements and punishment of today’s Nitro Fuels, Supercharged, Turbocharged, Nitrous Oxide, and Marine race motors....

Titanium Valves

Ferrea offers the finest titanium valve on the market. We manufacture each valve by forging a special high temperature titanium alloy with silicon. This high-temp alloy is considered a speical upgrade by our competitiors: however, it has been the standard material in all of our exhaust and intake valves for years....

Ferrea Valve Forging Process

In the production of our "one piece forging valve," the head of the valve is forged under a slow two-step process to avoid damage to the material structure. The forging piece is then machined entirely to eliminate any imperfection from the forging operation. Next is triple heat treatment, the stress-relief process, the grinding, and then the coating. Finally the valve stem is rolled to remove the rough scale and any gross imperfection on the surface. Ultrasonic tests and x-rays are then performed piece-by-piece to give each part a certified quality....

Lighter Equals More Power

Ferrea came out with Hollow Stem Lightweight Valves years ago revolutionizing the stainless steel valve market with a 22% lighter than your conventional stainless steel alloy valve. Made from exclusive Super Alloy materials, which they resist heat much better then conventional Inconel materials. Ferrea Hollow Stem Lightweight Valves are available in 7mm, 5/16, 11/32 and 3/8 stem diameters as well as semi finished blanks that we can machine for you application. Get the best in Valve technology today for your Race Engine!!!...
