PASTE FOR VALVE SEATS GRINDING

Paste for grinding the valve seats with trade name BEWIR was developed as a result of many-years‘ experience in POLOK WELDING company. As the company dealing with repairing the engine heads on a broad scale, we keep looking for possibly the best materials and technological solutions. The pastes available at the market did not meet our expectations, which made us take the research and tests on a completely new product. Paste BEWIR indicates very good properties, it has wide applications and meets our needs completely.

 

BUSHINGS ON VALVE SEATS

The valve seats produced by us may be easily used for combustion engines supplied with LPG, Diesel or petrol engines. The development of chemical composition was done by scientific workers, engineers, metallurgists and Polish design engineers of international respect. The full list of dimensions is available in our on-line shop www.sklep.polok.pl.

PRE-COMBUSTION CHAMBERS

Since there were no pre-combustion chambers in the market, in 2000 we started their production. At present, we produce the chambers for most models of Diesel engines both in nominal and oversize dimensions. On Customer’s individual order, we make the chambers for vary rare models and the chambers with untypical dimensions. The research work was taken and its results helped to develop the production technology providing the pre-combustion chambers with very high operating life. The full list of pre-combustion chambers is available in our Internet shop www.sklep.polok.pl.

 

INJECTORS HOLDERS

Since the injectors holders in oversize dimensions are very hard-to access in the market, we started the production of those components. We produce the injectors holders with both nominal and oversize dimensions, out of materials such as: copper, bronze, steel, cast iron. The holders are produced on individual orders or as the part of serial production, and are available in Internet shop www.sklep.polok.pl.
