SSV Valves Tagore Road, Rajkot, Gujarat

The valve guide enables valve movement and stroke as a consequence of acceleration by camshaft and keeps the valve in the center of the valve seat. Valve guides are used to shoulder the side forces operating on the valve stem. They conduct part of the combustion heat from the valve head to the cylinder head. These extreme loads define the correct choice of material with appropriate characteristics for the valve guide, which is of critical importance for product quality.   The key characteristics of materials used for valve guides are low friction and high thermal conductivity. We are capable of manufacturing Engine Valve Guide , usually made from cast iron, aluminium bronze valve guide and Brass material valve guide.

Titanium engine valves are used mainly in the high performance racing industry. SSV titanium engine valves are manufactured using best quality TI alloys. Titanium valve offers high temperatures resistance to assure peak performance. SSV is having all Titanium High Performance Series.Also featuring single or multi-layer coating such as chromium nitrite (CrN) or titanium nitrite (TiN), for increasing life span for highly heat resistance. SSV produces titanium engine valves for all high performance racing applications, from American countries, European countries, through professional sport applications.

The Swirl Polished Engine Valves are mostly used in high performance racing    engines.The swirl polished Valve has sharp edges and improves the flow, increases    the speed doesn't matter in which direction the swirl is.These valves are stronger    than non polished valves.

  The regular alloy material is used in manufacturing of these valve. There are two types of steel, Austentic steel and Martensitic steel. Some valves are magnetic and some valves are non magnetic depending upon the engine sustaining the valve.

  Engine Valves are plated with phosphate for maintaining lubrication and protect against corrosion.

Nitration is hardening process of coating nitrite on the engine valve which will appear as black valve. Compared to stainless steel base material the micro hardness is higher having high ductility property beneath the nitrated layer. The nitrite coating increases the deterioration and corrosion resistance. The Black Nitrite applies to the whole valve and the nitrite layer is stick to the base material at a microscopic level, so the valve does not break when in bend due to impacts with the pistons. Nitration processed on valve decreases stickiness and this features lengthen valve durability.

INCONEL alloy 751 (UNS N07751) is a precipitation hard enable nickel-chromium alloy, used mainly for the exhaust valves of internal combustion engines. The alloy has essentially the same excellent physical, mechanical and corrosion-resistance properties as INCONEL alloy X-750.In the evaluation of materials for exhaust valve applications, nickel-chromium alloys have performed well in a 1675°F (913°C) lead oxide screening test. INCONEL alloy 751 repeatedly offered good results, with corrosion rates averaging 4.31 g/dm2/h. Like other nickel-chromium alloys, INCONEL alloy 751 also resists attack by other exhaust stream impurities such as sulfur, bromine and chlorine.

Deflector Engine Valve   The Deflector Engine Valves are also manufactured maintaining the best Quality.

  The Chrome plated Engine Valve are manufactured by plating chrome on the stem of the valve. It lengthens durability in the valve and increases stem resistance.

The engine valve made up of two different metals are knows as bi-metal Valves. This is done using friction welding process. Exhaust valves are especially made from bi-metal. Austentic Steel which is having heat resistance and corrosion resistance properties, is used at the head while the stem is made from Martensitic Steel which have high tensile strength and abrasive wear resistance property. This technique is mainly used in high stressed exhaust valves.
