About Project

Uday Valves offers the most complete range of high-quality and performance Engine Valves in the industry. Engine Valve – a very critical part of the engine – performs in an environment of intensely harsh conditions where it is subjected to severe vibration, high temperatures, and destructive friction. In order to withstand these conditions for years, the engine valve must be made from carefully formulated, high-quality materials. Our engineering knowledge and experience in the field of internal combustion Engine Valves enables us to provide customers with a proper valve that features the necessary qualities that are required in order to perform at the anticipated efficiency, durability and lifespan.

Uday Valves offers high performance Engine Valves based on OEM specifications or as per custom specifications to suite customer needs. We produce Engine Valves for OEM and the Aftermarket — always according to the same strict quality standards. Today we employ state-of-the-art production technologies to manufacture more than 3500 types of Intake and Exhaust Engine Valves from a wide range of materials for most demanding applications. Our product range includes Engine Valves of diverse designs and types for various applications with Stem Diameters from 4 to 25 mm and Valve Lengths from 60 to 400 mm. With regard to their applications, our high performance Engine Valves are induction hardened, chrome-plated, or nitrided according to the requirements. A wide range of standard materials as well as specialty materials are available for custom requirements.
