Quality, productivity and technical research: these are the core values of our company, which is present in the original equipment and spare parts markets.


Tecnostar constantly monitors its manufacturing process, by using an advanced quality control system which complies with international technical regulations, including UNI EN ISO 9001:2008.


Non-original parts are becoming worryingly widespread, particularly on the spare parts market. With the support of hi-tech laser technology, Tecnostar now brands its products.

The product

Tecnostar produces over 6 million valves every year; just under half of these are destined for the spare parts market. Production includes valves and valve-guides for the engines of passenger vehicles and medium and heavy goods vehicles.


We have also been present on the international spare part market for many years and our valves are sold in over sixty countries worldwide.
