In 1991, S.B. International, Inc.® entered the Aftermarket Engine Valve arena and became the Marketer and Supplier of its now famous E-LOY® Brand Engine Valves. The SBI® E-LOY® Brand Of Engine Valves quickly became as legendary as its J-LOY® Valve Seat Inserts and indeed, the Legend lives on today! All E-LOY® Engine Valves are manufactured utilizing the latest Processes, Techniques, Statistical Processing & Highest Quality Standards available in the industry today. The E-LOY® Brand Engine Valve Materials that are used consist of Austenitic (Non-Magnetic) or Martensitic (Magnetic) Steels and Nickel-Chromium Based Super Alloys along with other Cobalt, Iron and Nickel Based (Stellite®) facing alloys which have been designed to run in modern Unleaded, Diesel and Gaseous Fuel Engines. Chrome Plated & Nitride Valve Stems are available where specific engine applications require it. Oversized Valve Stems are available in certain applications and are indicated by a suffix of +3 (+0.003") and +15 (+0.015"). To this day, SBI supplies the most comprehensive Model Coverage in the industry.
Including offering the most comprehensive Model Coverage in the industry, SBI supplies Valves for OEM Converted CNG & LPG engines as well as Valves for the most popular Aftermarket converted engines and coverage for Gaseous Fuel engines used in Automotive, Heavy Duty & Industrial Applications. In these Gaseous Fuel applications, the Super Alloys that are used are an oxidation and corrosion resistant material well suited for service in extreme environments that are subjected to higher combustion pressures and temperatures. These types of engines require specific Valve Materials and/or Facing Alloys along with the Correct Valve Seat Insert Materials in order to Maximize Service Life while operating in these extreme environments and conditions. The replacement of ONLY the Valve or ONLY the Valve Seat Insert can often cause problems for the Rebuilder as one mismatched component will often cause the mating component to fail. It is not safe to assume that a worn Valve is all that needs to be replaced. The worn Valve may be caused by the use of an incorrect Valve Seat Insert Material in that application. If you are not sure if the mating component is correct for the type of fuel being used, contact the SBI Technical Department and remember, it is always recommended to replace BOTH components at the same time.
SBI Domestic Performance Valves have been designed and constructed Using the Highest Quality Stainless Steel with Special Features that improve their operational performance over Standard Stock Valves. All SBI Domestic Performance Valves feature Single Keeper Groove designs. Longer stems are available for popular Small Block and Big Block applications. It is recommended all SBI Domestic Performance Valves are installed with a .002” Minimum Stem-To-Guide clearance. See The SBI® Performance Catalog To Find The Right Valve and mating components for your needs.
