What is is the purpose for a schrader valve?

A Schrader valve is a type of valve commonly used in tire inflation and fluids management systems. Its primary purpose is to allow air or gas to enter a tire or system while preventing it from escaping. The valve consists of a spring-loaded pin that opens when pressed, facilitating easy inflation or deflation. Schrader valves are widely found in automotive applications, bicycle tires, and various other inflatable products.
