Microtech Industries manufactures engine valves which are designed to meet international standards and thus they come with the promise of best quality. We offer the most complete range of high-quality and performance Engine Valves in this sector. We also custom design Engine Valve to match the exact specifications of vehicle manufacturers with due consideration to after-market requirements. The valves are made with carefully formulated and high-quality materials based on the OEM specifications or as per the customer specifications to suite the customer needs. Our strict quality check process ensures that every Engine Valve manufactured by us is efficient to overcome various thermal and corrosive loads for the years to come. With the use of best-in-class magnetic and non-magnetic steel, we produce a product that is trouble free and long lasting.
Engine Valve, being the 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. Our engineering expertise and experience in the field of internal combustion Engine Valves enable us to deliver the products which bear all the necessary qualities, that are required by the automobile manufacturer, in order to perform at the anticipated efficiency, durability and lifespan. We are proficient with designing and developing engine valve technologies for manufacturers that require high quality valves for diesel and alternative fuel engines. Solutions such as hollow valve manufacturing, seat welding, salt bath nitriding, and continuous materials and coatings development overcome the issues of increased temperatures, combustion pressures, corrosion and seat wear.
For more than three decades now, Microtech Industries had been efficient in manufacturing the product range which includes Engine Valves of diverse designs and types for various applications with Stem Diameters from 4.5 to 25 mm and Valve Lengths from 50 to 400 mm. With regard to their applications, our high performance Engine Valves are induction hardened, chrome-plated, or nitride according to the requirements. A wide range of standard materials as well as specialty materials are available for custom requirements.
1 . All Valves undergo 100% inspection for critical characteristics and achieve Cp and Cpk values.
2 . Valves are made from OE specifications containing Martensitic & Austenitic Steel having High Creep Strength.
3 . Valves have Hardened Tappet End to sustain Excess Cyclic Load from Overhead Cams.
4 . The "MTI" lightweight Engine Valves offer better engine performance, improved fuel efficiency and meet changing emission norms.
5 . Withstand high peak firing pressure because of Flat Seat Valves for Heavy Duty Diesel Engines.
6 . Improved fatigue and corrosion resistance due to higher case depth of Nitride Valves.
7 . All our Valves are duly Heat Treated there by increasing toughness & wear resistance on Stem & Seating areas.
8 . Valves undergo 100% crack detection.
9 . All Complaint parameters cover with Firewall Control.
