Precision proportional control variable pump, quick to
respond and runs smoothly





1. The product line includes popular models like DG4V-3, DG4V-5, and DG5V, with electromagnetic switching that responds quickly and shifts smoothly without sticking.
2. It supports multi-digit functional selections, allowing for single-cylinder or multi-cylinder synchronization, fast and slow switching, and other action logics, with both AC and DC coils available.
3. It has standardized plate mounting dimensions, compatible with common valve block hole positions for easy equipment upgrades or replacements, and the valve core is wear-resistant to extend service life.
Widely used in construction machinery, forging equipment, wind power tooling, and forming machinery for oil circuit direction switching. Leveraging brand agency advantages, original valve components are well-stocked. The products undergo directional durability tests as well as high and low temperature simulation tests before leaving the factory, ensuring stable operation even under conditions of heavy dust and fluctuating temperature differences. They can be purchased individually as maintenance spare parts or integrated into complete valve assemblies and hydraulic systems for turnkey delivery, significantly simplifying the design of the hydraulic circuit for the entire machine.
