SV PILOT OPEARATED SERIES SOLENOID VALVES

Solenoid valve is an automatic valve that controls the direction of fluid flow using electromagnetic principles. It is considered an actuator. The electromagnetic valve works by utilizing the electromagnetic force generated by the electromagnetic coil to move the valve core, thus opening or closing the gas source, which changes the direction of fluid flow. There are many types of solenoid valves. Based on their working principle and structural characteristics, they can be divided into direct-acting electromagnetic valves and pilot-operated electromagnetic valves. A pilot-operated valve is actuated by the pilot pressure output from the pilot valve, which moves the valve core. In contrast, a direct-acting electromagnetic valve uses solenoid force directly to move the valve core.
Pilot-operated electromagnetic valves are suitable for applications involving larger diameters and higher medium pressures. These valves are widely used, not only in hydraulic or pneumatic systems but also in various industrial control systems, where they adjust the direction, flow rate, speed, and other parameters of the medium, ensuring precise control and efficient operation of the system.
