A direct acting solenoid valve operates through a direct mechanical interaction between an electromagnetic coil and a valve element. Unlike pilot-operated solenoid valves that require external pressure to function, direct acting valves are powered directly by the solenoid. This characteristic makes them ideal for applications requiring fast, reliable operation and control of small flow rates or low-pressure systems. Their versatility and precision make them indispensable in industries such as fluid control, automation, air conditioning, and medical devices.
