Applications are divided into 3 printed catalogs – “Heavy Duty, Agricultural and Industrial” applications are in one catalog, “Light Duty, Medium Duty, and Marine” are in a second, and the 3rd catalog contains “QualFast” and “Black Lightning” performance applications. All catalogs can be downloaded via the Online Catalog page in .pdf form, or the Online Catalog contains all applications for all type of engines. Light Duty applications can also be searched for by Year, Make, Model and Engine.


A variety of alloys to suit all applications. These include carbon steel, martensitic steel with chrome and silicon, stainless martensitic, stainless austenitic, Inconel and Nimonic.

Engineered Features:
One-piece construction for most applications. These OE spec materials are designed to handle the extreme hostile environment of engines at full operating temperatures.

On Heavy Duty applications we also offer bi-metallic construction to gain the best properties of two different OE spec materials for thermal resistance (head) and mechanical resistance (stem and tip). Hard chrome-plated stems where required, to reduce stem wear. Stellited seats where required (denoted by an "S" suffix), to avoid corrosion caused by combustion gases. Welded wafer tips to resist friction of dynamic load. Some tips are also stellited.

Assured Quality ISO 9002 and QS9000. All QualCast valves are subjected to rigorous QA inspections both at the manufacturing plants and at our central distribution operation in Nashville, Tennessee, U.S.A.
