The valve guide centers the valve on the valve seat insert and conducts a proportion of the heat from the valve head, via the valve stem to the cylinder head. Due to this extreme strain, for the valve guides mainly the material and its properties are a decisive factor for the product quality. Production Capacity 30000 pieces per month *Believe in Quality not Quantity MaterialsValve guides are made of materials with good gliding and thermal conductivity properties. Grey cast iron and brass materials with selected alloy components have been particularly proven. Valve Seat Inserts https://www.rr-industries.co.in/valve-seat-inserts.htm https://www.rr-industries.co.in/valve-seat-inserts.htm Tue, 02 Nov 2021 00:00:00 +0530 The valve seat insert prevents the impact/burying of the valve into the cylinder head. It absorbs a proportion of the combustion heat with which the valve is charged. The valve seat insert gives off this heat to the cylinder head. To meet the different strains, an optimum material composition of the valve seat inserts must be found. Not only must the operating conditions in the engine be considered, but also the machinability of the material for the engine reconditioned. Valve Seats are made from High Quality Chromium and Nickel. Valve Seats ground surface is maintained 15 to 20 microns and face parallelism @ 10 microns. 100% dimensions Inspection and Visual Inspection of Valve seat Inserts. Hardness of Valve Seats must be 30 to 35 HRC. MaterialsIn the most recent engine generations of renowned car manufacturers, valve seat inserts made of sintered material (powder metallurgical procedure) are used. The increasingly high, thermal strain of the seat insert in the combustion chamber can hardly be met anymore by materials from conventional casting processes. For this reason, Motorservice offers sintered valve seat inserts amongst others from two different material combinations, which covers the entire application range of future engines.

Valves are mechanically, highly strained components which are additionally subject to corrosive influences The outlet valve is additionally heated by the passing hot exhaust gases during outlet clock opening. The valves are cooled down mainly by conducting heat via the valve seat insert to the cylinder head. The smaller proportion of the heat is conducted via the valve guide to the cylinder head. Inlet valves reach temperatures of approx. 300 °C to 550 °C, outlet valves can get up to 1,000 °C The Engine Valves are made up of heat resistant alloy. Various processes like Chrome flash on Stem Satellite on seat and tip area, Nitriding / Tuft riding are offered. The machining of outer diameter and radius of engine valves are processed on CNC Machine. Production Capacity 10000 pieces per month *Believe in Quality not Quantity. Types of ValveIntake Valve Mono-Metal valve Bimetallic valve Bimetallic valve with seat armoring Mono-Metallic ValveMono-metallic valves are only made from one material. For this, one material is chosen that is suited to both requirement profiles, namely high heat resistance and good sliding properties.Exhaust Valve Mono-metallic valve Bimetallic valve Bimetallic valveBimetallic valves enable material combination of a highly heat resistant agent (headpiece) with a skirt material which can be hardened on the one hand (skirt end) and also has good sliding properties for valve guidance. The materials are combined through friction welding.Dimensions & Technical Terms Total Length Total Valve head thickness Seat Height Height of valve seat face Seat Mourning Valve Head Skirt diameter Valve stem Groove diameter End face of stem (hardened) Grinding length Throat Valve seat angle Head surface Head diameter Culotte Air Cooled Cylinder Blocks https://www.rr-industries.co.in/air-cooled-cylinder-blocks.htm https://www.rr-industries.co.in/air-cooled-cylinder-blocks.htm Wed, 27 Oct 2021 00:00:00 +0530 Brake Drums https://www.rr-industries.co.in/brake-drums.htm https://www.rr-industries.co.in/brake-drums.htm Wed, 27 Oct 2021 00:00:00 +0530 Cylinder Liners and Sleeves https://www.rr-industries.co.in/cylinder-liners-and-sleeves.htm https://www.rr-industries.co.in/cylinder-liners-and-sleeves.htm Wed, 27 Oct 2021 00:00:00 +0530 Cylinder sleeves https://www.rr-industries.co.in/cylinder-sleeves.htm https://www.rr-industries.co.in/cylinder-sleeves.htm Sat, 05 Feb 2022 00:00:00 +0530 Cylinder liner and sleeves for every model.
