The PARADOWSCY AMP company proved itself as a producer of high quality parts for internal combustion engines. Along with impeccable engine valves AMP is introducing the valve guides of the same high standard.
The material used for the production of guides is gray cast iron Grade 200 (EN-JL 1030), characterized by high resistance to heat and good conductivity. This allows efficient removal of heat from the cooled cylinder head.
Valve guides made of aluminum bronze BA 1032 PN are provided for heavy-duty engines. This type of bronze alloy is one of the most durable. It is used to counteract the effects of high temperatures, cavitation and rust.
Choosing material for the production of valve guides, the operating conditions of this subassembly must be taken into account, such as: high speed of valve movement in the guide sleeve, exposure to high temperatures and limited oil level in the valve-guide system.
