Danfoss Power Solutions has launched its DVG family of hydraulic valves, a new line of open-center directional control valves for mobile machinery. The valve group brings a new level of quality and performance as well as rapid and reliable delivery to a competitive market. DVG 60 and DVG 100 valves are ideal for a variety of construction, material handling, and agriculture machinery, including skid steer loaders, compact track loaders, backhoe loaders, truck-mounted cranes and tractors.

Danfoss DVG valves offer several class-leading performance attributes, including return flow rate, pressure drop, and active spool stroke resolution. DVG valves are designed with meter-out flow 75 per cent higher than meter-in flow at 15 bar pressure drop. This enables fast cylinder re-traction to meet desired cycle times, eliminating the need for complex or oversized systems. Pressure drop from the valve inlet to the work port is 33 per cent lower in a DVG 60 valve and seven per cent lower in a DVG 100 valve compared to the next best alternative.

With 4.2 mm of active spool stroke resolution on proportional electrohydraulic controls, DVG 60 and DVG 100 valves provide better application controllability than other open-center valves on the market.

The modular build concept is a key feature of the DVG valve family. A common interface for the DVG 60 and DVG 100 valves enables flexible configuration to meet each machine’s precise requirements. A maximum of 12 work sections can be combined in one valve, enabling use on machines with a range of functionality.
