A piston valve is a mechanical valve used to control and direct the flow of fluids such as steam, air, or liquids in engines and industrial machinery. It consists of a cylindrical piston that moves back and forth inside a closely fitted valve chamber. As the piston reciprocates, it covers and uncovers ports, allowing fluid to enter and exit at the correct time. This ensures proper timing, pressure regulation, and direction of flow.
