What is a parachute valve?

A parachute valve is a type of valve used in various applications, particularly in the aerospace industry, to control the flow of fluids or gases. It operates by using a flexible membrane or flap that opens and closes based on pressure differences, allowing for precise regulation of flow. The design is similar to a parachute, which deploys to slow descent, ensuring safety and stability in its function. Parachute valves are often employed in systems where rapid response and reliability are critical, such as in fuel systems or hydraulic circuits.
