INA Valve Tappet

INA Valve Tappet

Ensures the right movement

Product description:

All valve tappets do the same thing. They keep the clearance between the camshaft and the valves – resulting from wear and thermal expansion – as small as possible, which allows for safe power transmission. With classic hydraulic tappets this is realized via cam stroke which strikes the valve directly. This gives rigid drive attributes and achieves very fast valve response.

INA is the world’s largest supplier of valve tappets to the automotive industry. Through a specially-developed 3CF architecture and state-of-the-art coating, INA Tappets operate with minimal friction. INA’s product portfolio ranges from hydraulic bucket tappets, to mechanical and hydraulic pivot elements, all the way to hydraulic insert elements.
