About Osvat: Six Decades of Italian Valve Engineering

Few names in engine valve manufacturing carry the heritage and precision that Osvat does. Founded in 1960 in Piobesi Torinese, in the Piedmont region of northern Italy, Osvat S.r.l. has spent over six decades doing one thing exceptionally well: producing high-quality engine valves for internal combustion engines. What began as a single-focus operation has grown into a globally recognized manufacturer trusted by engine builders, professional mechanics, and OEM suppliers alike.

The company's roots trace back to its founder, Mr. Griffa Giuseppe, and the business has remained privately held and family-guided ever since — a continuity of ownership that has instilled a deep commitment to craftsmanship and consistent quality. Today, Osvat operates manufacturing facilities both in Italy and Romania, with a combined output of between 8 and 10 million valve pieces per year, covering applications ranging from small motorcycle engines all the way to heavy earth-moving equipment.

Quality and Technology at the Core

Osvat's reputation is built on precision. The company uses only certified European and American steels — including chrome-silicon and high-alloy grades — and manufactures exclusively on CNC machinery developed in partnership with its own engineering teams. Computer-aided design (CAD) ensures dimensional accuracy at every stage, and a fully equipped quality-control workshop monitors critical tolerances throughout production. This unwavering focus on precision engineering is why Osvat parts are a go-to choice for head rebuilds and engine restorations worldwide.

Quality certifications reinforce what Osvat's products demonstrate on the dyno: the company holds ISO 9001 and ISO 14001 certifications, both awarded by TUV, reflecting its dedication to both product quality and environmental responsibility. Osvat is also a TecDoc-certified data supplier, making it easy to find the right valve for virtually any vehicle application.

An Extensive Catalog for Every Engine

With over 8,000 individual part numbers in its catalog, Osvat covers an extraordinary breadth of vehicles — European marques like Alfa Romeo, BMW, Fiat, and Volkswagen sit alongside Asian and American applications spanning passenger cars, light commercial vehicles, trucks, and agricultural machinery. Whether you are sourcing for a classic European sedan or a modern diesel workhorse, Osvat almost certainly has a valve specification to match.

The two pillars of the Osvat catalog are its Engine Exhaust Valves and Engine Intake Valves. Together, these product lines represent some of the most precisely engineered valve solutions available in the aftermarket, built to OEM dimensional standards and verified through rigorous quality processes. For any engine builder looking to combine Italian craftsmanship with broad vehicle coverage, Osvat is the clear choice.
