  Valve Guide

Old-fashioned production model valve guides may lead to higher emission values when used in highly tuned engines. Sumangal Manufacturer & Export valve guides bring a noticeable reduction in pollution emissions. Our own research confirm and long-term scientific tests proved this. Brass valve guides are characterised by a good cutting property. Sumangal Manufacturer & Export's valve guides are symbol of economically efficient manufacturing and the customized solution for our customers.

Sumangal Manufacturer & Export Valve Guides are proposed with the following types of material:
G = pearlitic grey iron with good resistance to wear, suitable for applications with normal stress levels.
G1 = pearlitic grey iron with added phosphorus, which forms a lattice significantly enhancing resistance to wear even when lubrification is poor, thanks to its anti-friction properties.
G2 = grey cast iron with pearlitic laminar matrix combined with phosphorus and chromium. The phosphorus gives the grey cast iron resistance against wear, while the chromium improves its properties for use at high temperatures. Suitable for utilizations characterised by high strain.
B = aluminum brass alloy with high resistance to wear, good resistance to fatigue and corrosion, suitable for applications with medium stress levels.
B1 = phosphorus bronze alloy combining high resistance to wear and high thermal conductivity with good anti-friction properties; suitable for applications with high stress levels.
Cu = copper alloyith high hardness and thermal conductivity, and high resistance to wear and abrasion. Its excellent mechanical properties assure good resistance in heavy duty conditions.

Valve Guides in sintered steel - Sint 01, Sint 03, Sint 06
S01 = this copper molybdenum alloy is characterized by its elevated mechanical resistance that is also maintained at extremely high temperatures, which is joined by particles of lubricating material shrouded in alloy which tend to eliminate the cause of the phenomenon of wear due to shifting thus making it suitable for all types of use, even severe.
S03 = steel alloy featuring tin-phosphorus elements able to ensure mechanical strength and significant self-lubricating power. Compared to traditional material versions, Sint 03 valves guides do in fact show lower inertia in forming the hydrodynamic lubrication film on ignition and thus ensure excellent resistance to sliding wear. Sint 03 sintered steel is able to maintain these properties even in heavy-duty working conditions such as those found in latest-generation engines. These valve guides have been developed for all high-performance induction and supercharged engines - petrol, diesel and gas.
S06 = copper/sulphur alloy with good self-lubricating power and and wear resistance to glide under the working conditions to which the parts of high performance engines fueled with petrol, gas-oil or gas may be subject.
