What Is a Poppet Valve?
A poppet valve is a type of valve used for fluid control and gas control.
It consists of a rod-like part called the “stem” and a circular or elliptical “poppet” lid that controls the opening and closing of the valve. By moving the entire valve along the axis of the stem, the gap between the valve seat and the poppet part changes, allowing for the control of fluid or gas flow. Poppet valves are commonly made of materials such as stainless steel, brass, aluminum alloys, or ceramics.
They are employed in various applications, including engine intake and exhaust systems, pressure control devices, liquid pipelines, pneumatic equipment, liquid pumps, and cooling systems. Key features include rapid opening and closing, robustness, and improved sealing performance.
