Valve guide K25 Engine Piostion Valve 13212-FY500 For Nissan

Product Features

The valve guide is an important component in the engine, used to guide the intake and exhaust airflow, and connect the valves and valve seats. The following are some common features of valve guides:
Material: Valve guides are usually made of high-temperature resistant and wear-resistant materials, such as cast iron, steel, or titanium alloy. These materials can withstand high temperature and high pressure environments and have good durability.
Diversion characteristics: The design of the valve guide is aimed at optimizing the flow characteristics of the airflow to provide the best intake and exhaust efficiency. The curves and angles inside the conduit affect the speed and direction of the airflow to ensure appropriate valve opening and closing behavior.
Sealing performance: The valve guide needs to have good sealing performance to ensure normal sealing between the valve and valve seat and prevent gas leakage. Sealing can be achieved through the fit between the guide tube and the valve seat, as well as the use of sealing rings or gaskets.
Wear resistance: Valve guides need to have good wear resistance because they will experience high-frequency friction and wear during the opening and closing process of the valve. Proper surface treatment and material selection can improve the wear resistance of the conduit.
Size and geometry: The size and geometry of the valve guide depend on the specific engine design and application. They need to fit well with the engine's valves and valve seats to ensure correct installation and operation.
