What is a valve? DSH Seals tells you! The role of the valve is to feed air into the engine and discharge the exhaust gases after combustion. So the engine structure must be managed by two valves: First, the intake valve (intake valve) the role of the intake valve is to draw air into the engine, and fuel mixture combustion. Second, the exhaust valve (exhaust valve) the role of the exhaust valve is the combustion of exhaust gases out and heat.
What is a valve stem seal? Valve stem seal (Valve stem seal) is also known as a valve oil seal. It is generally made of vulcanised outer skeleton and fluoroelastomer, with a self-tightening spring or steel wire at the diameter of the mouth, and is used to seal the engine valve guide rod.
It can prevent the oil from entering the intake and exhaust pipe, causing oil loss, preventing the mixture of gasoline and air and emission exhaust gas leakage; and preventing the engine oil from entering the combustion chamber. The valve oil seal is one of the most important parts of the engine valve train and is in contact with petrol and oil at high temperatures. Therefore, it is necessary to use materials with excellent heat and oil resistance, generally made of Viton.
