Product Overview
▔▔
Yuken's solenoid-operated directional valves (such as the popular DSG series) are designed to provide high pressure, high flow rates, and low pressure drops. They utilize powerful wet-armature solenoids that ensure smooth operation and long product life.
Key Advantages
▔▔
- High Pressure & Flow Capacity: Engineered to handle high-flow systems without sacrificing stability.
- Low Pressure Drop: Optimized internal flow passages reduce energy loss and heat generation.
- Wet-Armature Design: The solenoid moving parts are immersed in hydraulic oil, providing natural lubrication, quieter operation, and protection against dust and moisture.
- Shockless Operation (Optional): Available with specialized spools that minimize hydraulic shock (fluid hammer) during switching, protecting your piping.

FAQ
▔▔
Q1: What is the benefit of a "wet-armature" solenoid design? A: In a wet-armature solenoid, the core is submerged in the system's hydraulic oil. This layout eliminates the need for an external push-pin seal, which is a common leak point in older valve designs. It also dampens the impact noise when the valve shifts.
Q2: Can I use a DC solenoid coil on a valve originally bought with an AC coil? A: Yes, but you must replace the entire solenoid assembly (the coil and the tube), not just the plastic coil outer shell. The internal armature tubes are shaped differently for AC and DC currents.
