5 port 3 position pneumatic valves are essential components for controlling double-acting cylinders in industrial automation. These valves feature five connection ports and three distinct spool positions, allowing for precise control of air flow. The centre position can be configured as closed, pressure, or exhaust, enabling functions such as holding, floating, or venting the cylinder. They are commonly used to stop a cylinder in an intermediate position or for safety applications, offering versatile control for various pneumatic systems.
