Prince Engine Valves

We are pleased to introduce ourselves as one of the trusted manufacturers, suppliers and exporters of Engine Valves. The offered valves are used these for optimum performance for longer period of time at extreme temperatures and rusty surrounding under high dynamic load. Offered valves are manufactured using optimum quality stainless steel and other alloys in order to meet the international quality standards. To ascertain the quality of the offered product, these Engine Valves are thoroughly checked on certain well defined parameters of quality testing such as durability.Features:Easy fittingDimensional accuracyFine finishCorrosion resistant Other info:Engine Valves Prince Valves offer one of the widest range of Intake & Exhaust Engine Valves for Internal Combustion Engines. Globally accepted special steel of heat resistant alloy is used for Engine Valves to perform reliably over long period at elevated temperatures and corrosive environment under high dynamic load. Intake and Exhaust valves are offered from a wide range of materials such as: En52(SUH 1/SUH 11) for Inlet Valves and Austentic Steel 21-4N(SUH 35) or Bi-Metal for Exhaust valves with stem dia from 4mm to 20mm and Head dia from 20mm to 250mm and length up to 500mm. To ensure uniform mechanical properties of steel the material passes through proper Heat Treatment process. Valve stems are chrome plated or Tuff Trided/Nitrided to increase surface hardness of the stem & resistance to corrosion of lubrication. Valve seat portion and tip are hardened by special Induction hardening process to increase the corrosion and wear resistance. Focusing briefly upon our production units, we have extensive research & development facility. The infrastructure fully equipped with special purpose sophisticated machines with the latest and advanced CNC technology. Cotter & grooves are made on a special purpose turning machine with in close tolerance & accuracy. Seat grinding is done on a special purpose machine to ensure consistent concentricity & cylendricity to match the International standard. An independent set up with dedicated team of technocrats and different in-house facilities for production & quality control attribute the maintenance of high quality standards laid down by ISO and meeting the demands of the OEM customers.
