About Us

Take me directly to Range of services

Intervalves Technologies AG is a Swiss manufacturer of premium inlet and exhaust valves for all types of combustion engines. Applications include cars, motorcycles, trucks, locomotives, earth moving equipment as well as stationary, marine and aeronautic engines.

Intervalves Technologies serves customers in both the OE and IAM segments of the market.  

For aftermarket (IAM) customers (parts distributors and engine rebuilders), over 1’500 references are available from stock. The Intervalves Technologies catalogue is available on TecDoc as well as on the company website, where a search function helps to find the right valve for a given application. In addition to the stocked items, a further 5’000 designs are in our database and can be reproduced on request.  Existing valves can also be reproduced using a sample or a design provided by the customer.

For OE customers, new valves are calculated and designed in close collaboration with the customer. Prototype, pre-series and series valves are produced in the required quantities and evaluated by both partners.

All Intervalves Technologies AG valves are entirely produced in Biasca / Switzerland.
