Power Industries - Manufacturer & Exporter Of Engine Parts





Power Industries India has been designing and manufacturing premium and high perfomance engine valve guides for automobiles of all make and model for more than 5 decades. We are recognized as a world's leading manufacturer of engine parts. We use Grey cast iron alloy with high phosphorous content to manufacture our valves and that gives our valves high endurance and tolerance even under poorly lubricated conditions.

We are a trusted name amongst engine experts and engineers all over the world and are one of the leading Engine Valve Guides Suppliers in India and across the Globe.

At Power Industries our experts ensure that the finished products are precisely built and comply with the accurate dimensions on the inner bore, to ensure that it's a perfect replacement for original part. The main function of the Valve guide is to conduct the heat out of the exhaust valve onto the cylinder head where it is dissipated by the cooling system of the vehicle. The Engine valve guides are integral to a engine's proper performance. The use of high phosphorous grade in the material results in optimum play and life.

Engine Valve Guides

We are manufacturer of Valve Guides for Petrol, Gasoline and Diesel Engine with QUALITY our main objective and which is the reason for our success in the valve guide business.

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 BHNRANGE OF VALVE GUIDES.

The range of engine which we include are two wheelers, four wheelers Trucks, Buses, Marine Engine, Earthmoving Engines, Tractors, Generator, Excavation Engines, Industrial Engines, stationary engines. The material of the Valve Guide we use depends on the type of Engine and the speed and the effort of engine

  • Tin Bronze ( North American UNS C90500, German CuSn10Zn, British G1) for piston airplane engines.
  • Aluminum bronze (North American UNS C95400, German CuAI10Fe, British AB1) for high temperature applications.
  • Aluminum Silicon Manganese Bronze for High Speed Engines.
  • Other alloys such as manganese bronze and leaded phosphor bronze have been used sporadically.
  • Other alloys such as manganese bronze and leaded phosphor bronze have been used sporadically.
  • Graded Cast Iron of 25 & 30 Grade. This Cast Iron is specially made for High Racing Engine.

We undertake new development of Valve Guide as per buyer's drawing/specification.


A Valve Guide is a cylindrical piece of metal, pressed or integrally cast into the cylinder head, with the valve reciprocating inside it.

Guides also serve to conduct heat from the combustion process out from the exhaust valve and into the cylinder head where it is taken up by the cooling system.

The hollow between the inner Diameter of the valve guide and the outer diameter of the valve stem is important for the good performance of the engine.

If the hollow is large the valve may not seat properly and excessive oil consumption can occur and overtime will deform.

Dimension Range (in mm)
Inner Diameter 5.00 TO 28.00 MM
Outer Diameter 8.00 TO 30.00 MM
Total Length 25.00 TO 300.00 MM
