Description

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.


5000 Performance Series

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. They feature a one-piece forging made from stainless steel, a special heat treatment process, hard chrome stems, and hard tip.

Most applications are available in an undercut stem and dished head, while other applications are available in straight stem and flat head. These valves provide our customers with maximum value for their dollar, and are designed for Street Performance engines, mildly modified Drag and Oval Track applications.

These valves are available for both the traditional Domestic performance and racing engine market and the Sport Compact performance and racing market. Many of the 5000 series valves feature flat combustion chamber faces to help increase compression in naturally aspirated engines.


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 1600F) and in the intake manifold area (up to -25F), 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.
