Our lightweight engine valves offer better engine performance, improved fuel efficiency to meet the changing emission norms. It improves fatigue and corrosion resistance due to higher case depth of nitride valves. All our valves are duly heat treated, thereby, increasing toughness and wear resistance on stem and seating areas. These valves are made from OE specifications with proper testing that undergo 100% inspection for critical characteristics. They also undergo 100% crackdetection tests.
