The DSG-02-3C2-1W-R220 is a high-performance, solenoid-operated directional control valve designed for precise and reliable operation in industrial hydraulic systems. This 4-way, 3-position valve features a “Closed Center” (3C2) spool configuration and is actuated by a powerful 110VAC (R220) single solenoid.
Part of the renowned DSG series, this compact and robust valve is engineered for durability in demanding environments. Its wet-pin AC solenoid design ensures cooler operation, longer service life, and excellent resistance to shock and vibration. The valve is ideal for applications requiring automatic control of double-acting hydraulic cylinders or motors.
Key Features & Benefits
-
Precise Directional Control: 4 ports (P, T, A, B) and 3 positions allow for advanced control of hydraulic flow, enabling extend, hold (center closed), and retract functions.
-
Closed Center Spool (3C2): In the neutral position, all ports (P, T, A, B) are blocked. This design traps fluid in the actuator, holding the load stationary without drifting, and unloads the pump.
-
110VAC Coil (R220): Standard industrial voltage coil for easy integration into existing control panels and machinery.
-
Single Solenoid, Spring Return (1W): The valve shifts when the solenoid is energized and automatically returns to the neutral center position when de-energized, providing fail-safe operation.
-
Wet Armature Construction: The moving solenoid parts operate in hydraulic oil, leading to reduced wear, quieter operation, and superior heat dissipation compared to dry designs.
-
Compact & Durable Design: The DSG-02 size is suitable for a wide range of flow capacities. Built with high-grade materials for long-term reliability.
