DMG Directional Valve FAQ:
1. What is the DMG Directional Valve ?
DMG directional valve is hand‑lever actuated spool‑type hydraulic directional control valve. It is sub‑plate mounted, available in spring‑centered or detent‑holding versions. It changes oil flow direction to control hydraulic cylinders and motors. Multiple spool functions optional, widely used for industrial and mobile hydraulic systems requiring manual operation.
2. What makes the DMG Directional Valve ?
DMG directional valve adopts hand‑lever manual operation without electric power. It provides two return modes: spring‑centered auto‑return or detent latching. ISO 4401 standard subplate mounting, multiple spool functions optional. Hardened spool ensures low internal leakage. Simple‑maintenance, robust structure for harsh industrial and mobile hydraulic working conditions.
3. What is the working pressure range of DMG Directional Valve ?
For DMG directional valve, the maximum working pressure for P/A/B ports is 31.5 MPa, and the maximum allowable back‑pressure at T return port is 16 MPa. It delivers stable performance under rated pressure for industrial and mobile hydraulic applications.
4. Can DMG Directional Valve replace other brands?
Yes, DMG directional valve can serve as a direct replacement for Yuken‑type DMG series manual directional valves. It complies with ISO 4401 standard subplate mounting dimensions. Compatibility depends on working pressure, nominal flow, spool function and lever return structure. Please verify these key parameters before replacement. Custom service is available if structural differences exist.
5. What is the Response / Switching frequency of DMG Directional Valve ?
DMG directional valve is hand‑lever manually operated valve without electric actuation. Switching action relies on manual operation. For spring‑centered version, spool reset time is approx. 0.05‑0.12 s. There is no fixed automatic switching frequency. Actual switching cycles are determined by operator operation. Oil viscosity and working pressure will affect spool movement performance. Not intended for high‑frequency automatic cycling.
6. Do you provide OEM or customized services?
Yes, OEM and customized services are available for DMG Directional Valve. We can customize spool functions, sealing materials, lever styles and valve marking according to your requirements. Please provide detailed specifications or drawings for accurate quotation.
7. How can I get a quotation quickly
Please provide the following details:
