PISTON VALVE

A piston valve is a type of valve used in various mechanical systems to control the flow of fluids, such as gases or liquids. It consists of a piston mechanism that moves within a cylindrical chamber to regulate the passage of the fluid through the valve.

The piston valve operates by moving the piston within the valve body, which opens or closes the passage for the fluid to flow. When the piston moves in one direction, it creates an opening, allowing the fluid to pass through. Conversely, when the piston moves in the opposite direction, it closes off the passage, stopping the flow of fluid.

Piston valves are commonly used in steam engines, pneumatic systems, hydraulic systems, and certain types of industrial machinery. They are known for their reliability, precise control, and ability to handle high pressures and temperatures.

These valves can be configured in various ways, such as sliding piston valves, rotating piston valves, or oscillating piston valves, depending on the specific requirements of the application. They are often chosen for applications where tight shut-off and precise control of fluid flow are essential.
