Product Description
SWH-G02 Series Double Head Solenoid Directional Valves
Product Overview: The SWH-G02 series is a high-performance, double-solenoid (double-head) hydraulic directional valve designed for three-position control of hydraulic actuators. Utilizing a direct-operated design compliant with ISO 4401-03 (NG6) international standards, this series is characterized by its long-life wet-pin solenoid technology. The double-head configuration allows the spool to shift precisely between three positions (left, center, right), making it a staple in machine tools, automated production lines, and industrial power units.
Featured models: SWH-G02-C2, SWH-G02-C2M, SWH-G02-C22M, and SWH-G02-C23.
Key Technical Advantages:
Precise 3-Position Control: The dual-solenoid setup combined with a spring-centering mechanism ensures the spool returns to its neutral position during power loss, facilitating complex control logics.
Wet-Pin Solenoid Design: The armature operates within hydraulic fluid, providing excellent heat dissipation and smooth switching without mechanical noise, significantly extending coil life.
Broad Voltage Compatibility: Available in D24 (24VDC), A110 (110VAC), and A220 (220VAC) options to meet global industrial power standards.
High Pressure & Protection: Built with high-grade cast iron for rated pressures up to 31.5 MPa, featuring IP65 rated electrical interfaces.

1. Axial piston pump with swashplate design for hydraulic drive in open circuit
2. Optional installation location
3. Excellent oil absorption characteristics
4. Low noise level
5. Long service life
6. Modular design
7. Short response time
8. Variable speed drive options
9. Visible swing angle indicator
10. The flow rate is proportional to the input transmission speed and displacement. By adjusting the swashplate angle, the output flow can be steplessly adjusted.
11. Use of HF oil in the case of reduced operating data There is a special model that can be used to run with HFC oil
