DSG-01 Solenoid Operated Directional Valves
These Solenoid Operated Directional Valves have achieved top-notch performance in high pressure, high flow, and low pressure drop. This is made possible by using a powerful wet-type solenoid and a well-designed flow channel system with five chambers.
High Pressure & High Flow Rate
Compared to our previous product lines, these valves show significant improvements in both pressure and flow.
Low Pressure Drop
These valves have a reduced pressure drop compared to our existing lines, which helps lower the unit's energy consumption.
Compact & Small Mass
Despite their high performance, these valve bodies are compact and lightweight, especially with DC double solenoids.
Shockless type available
Besides the standard high-pressure and high-flow valves, a shockless type is also offered to minimize noise and vibration during spool changeover.
Stable Operation
Thanks to the strong magnetic and spring force of the solenoids, these valves can operate stably even with contaminants.
