All 30- valve guides are individually cast in gray iron. Where required certain alloying materials such as chromium, molybdenum or nickel may be added. All guides meet or exceed OE material specifications.
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. RANGE OF VALVE GUIDES.
