rich with more than 18 years of experience in its specific sector manufactures engine valves, valve seat inserts and valve guides for combustion engines of automobiles, tractors, cars, generators, stationery engines, heavy commercial engines, motor cycles of various models and of different makes. Apart from being a leader in the domestic market, the company exports to different countries in Europe, Asia and Africa.
The success story of the company in the field of manufacturing of engine valves, valve seat inserts, valve guides and other components started in 1990 with a determined and dedicated team of technocrats and different in-house facilities for production and quality control for each product to attribute the maintenance of high quality standards laid down by ISO and meeting the demand of the OEM customers both in domestic and overseas market.
KRISHNA production lines are capable of stable and robust process manned by technically skilled persons with state-of-art testing and evaluation facilities to access the latest product and process technology with special purpose sophisticated machines.
The engine valves is made up of heat resistant alloy. krishna manufactured engine valves are reliable. The corrosive environment and high temperature cause dynamic load on the engine valve.
• Intake valves made from steel EN-52
• Exhaust Valves made from Austenitic Steel of EN-52 or Bi-metal.
The engine valve ensures that the mechanical properties of steel pass through the heat treatment process in the furnace. The chrome plate of tuff trided / nitrided engine valve stem is for surface hardness and resistance to corrosion of lubrication. Thus the engine valve seat portion and tip are hardened .Cottar and Grooves made by the engine valves are for turning machine within close tolerance and accuracy. Seat grinding is done to ensure international standards with concentricity and cylindricity.
Valve Seat Inserts extends the life of engine valve’s seat portion. Different types of materials are used to manufacture valve seat inserts. Special alloys of cast iron and chrome alloy steel are use to manufacture valve seat inserts. Intake seat inserts and exhaust valve seats are the types of valve seat inserts widely supplied by the company.
Exhaust valve seat have high wear resistance to high temperatures. Valve seat inserts are suitable for use in light alloy aluminum and cast iron cylinder heads. krishna industries are the foundry and have a chemical analysis laboratory to provide special alloy casting to deliver high quality valve seat inserts. Special tool room allows valve seat inserts to be made as per customer’s requirements/specifications. krishna inddustries also have complete machine shop equipped with special purpose machines and instruments for valve seat inserts production. All standards and sizes of valve seat inserts are made to match OEM and global specifications.
Valve Guides are made from gray cast iron alloy. These valve guides have high phosphorus content. This improves running of poor lubrication conditions in valve guides. Valve Guides have high wear resistance. krishna valve guides are also provided with thread and spiral in its inner dia. This helps to retain the oil for long time in Valve Guides and Engine Valves. krishna valve guides have long life and are maintenance free.
WE HAVE TOTAL AGRICULTURE PARTS PRODUCTION LIKE BUSHING, SPACER REEL CASTING ,ALL TYPE OF PULLY,AND ALL TYPE OF EXPORTS SEMPAL SEIRES,WE ABLE TO SUPPLY 50 TON CASTING PER MONTH
After a successful record for the last 25 years in the manufacturing of engine valves, valve seat inserts and valve guides now krishna has started manufacturing other components and parts like cylinder head gaskets, glow plugs, cylinder liners, rocker arms, camshafts, camshaft assemblies on regular demand and encouragements by their esteemed customers.
