3 Port 2 Position pilot valves are essential components within pneumatic control systems, designed to manage the flow of compressed air. These valves typically feature a single inlet, a single outlet, and an exhaust port, allowing them to control actuators or other pneumatic devices by directing air to one of two positions. They are commonly used in applications requiring simple ON/OFF control or the operation of single-acting cylinders. Understand their function and suitability for your industrial needs.
