Import Engine Valves For Steyr — Buy in Bulk from Supplier in China

These engine valves are designed for STEYR diesel engines, with a focus on compatibility with models used in agricultural and industrial machinery. The valves feature a heat-resistant alloy composition that meets OEM standards for thermal cycling, with stem diameters and head geometries matched to STEYR cylinder head specifications. Each unit is machined to tight tolerances to ensure minimal valve guide wear and consistent sealing under high-pressure conditions.

Material composition typically includes chromium-silicon steel for intake valves and austenitic stainless steel for exhaust valves, providing resistance to oxidation and corrosion at elevated temperatures. Standard surface treatments such as nitriding or chrome plating are applied to enhance durability, while valve face angles are precision-ground to 45 degrees for optimal sealing. The components are supplied in standard industry grades, with typical hardness values of 30-35 HRC for intake and 35-40 HRC for exhaust variants.

Primary buyers include agricultural equipment distributors, industrial engine rebuilders and OEM service centers in Europe, Africa and South America. The valves are packed in bulk cartons with individual protective sleeves to prevent transit damage, and are compatible with STEYR engines used in tractors, harvesters and stationary power units. Lead times and packaging details should be confirmed with the supplier, as these may vary based on order volume and destination port.
