Valve Guides

The valve guide is a part which supports the shaft part of a valve, maintains centre of the valve seat inserts thereby supporting the reciprocal Movement of the engine valve. Because the valve, which operates by high speed reciprocal motion, slides against the guide, high wear resistant is required in valve guides. Importance of Valve Guide is to efficiently make proper contact with the Valve. For valve guide Performance correct Material, Hardness and Dimensions are the vital aspects. The key characteristics of materials used for valve guides are low friction and high thermal conductivity. On the other hand, from the viewpoint of manufacturing, machinability has become an important property because the inner diameter is machined after the guide is press-fitted in the cylinder head. We produce Valve Guide, most made from special graded cast iron, at the same time special applications are having requirements of aluminium bronze and Brass materials, they are also available with ours stock.

Valve retainers

Valve Spring retainers are used with collets to lock the valve and hold it in accordance with the spring for the better performance. We manufacture this items in bulk quantities, it's a smaller but very important component of valve train.

Engine Valve Collets

The collets are used as a pair to hold the inlet and exhaust valves in the engine. These are used widely in all four-stroke internal combustion engines. The very important aspect for valve collets is to match with the groves of valve. It's a type of lock for valve to hold it in the same position not allowing it to move left or right side. Valve Collets we make in huge quantity, material for this used is 20mncr5.
