Product Overview
The SUNGSAN HI-TECH SS3761 / RTX-0062 is a solenoid-operated directional control valve engineered for precise hydraulic circuit switching in industrial and mobile hydraulic systems. Manufactured by SUNGSAN HI-TECH, a recognized Korean producer of hydraulic components, this valve utilizes an electrically actuated solenoid pilot to shift an internal spool, directing pressurized fluid flow between ports to extend, retract, hold, or reverse actuator motion. The SS3761 / RTX-0062 is designed as a direct-fit replacement for standard directional control valve configurations, offering reliable spool positioning, fast response, and consistent sealing performance in demanding duty cycles. It serves as a core control element in manifold-mounted and inline hydraulic circuits where accurate flow direction and dependable actuation are essential.
