We manufacture the Valve guide from the size range of 1" to 24".We manufacture valve guide for almost all size of Engine. Valve Guides are grounded to a surface finish of 0.80 Micro Ra on its Outer Dia and with in a tolerance of 13 Microns. Valve Guides are also provided with Thread and Spiral in its Inner Dia to retain oil for long time. Thus increases the life of both Valve Guide and the Valve.

The Valve Guide manufactured by us has microstructure of Pearlitic matrix with 5% maximum free ferrite 5% maximum free carbides and 10% maximum steadite in cellular or discontinuous form and Valve Guide has Hardness of 210-260 B.H.N. Single Metal, 2 Pcs. Construction (Bi-Metal), seat stellited & Tip Hard, stainless steels with or without tuff-triding, Hard chrome on stems.

Materials

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 , to avoid corrosion caused by combustion gases. Welded wafer tips to resist friction of dynamic load. Some tips are also stellited.
