The Walvoil DPC Series is a family of open/closed center pre-pressure compensated sectional valves designed specifically for mobile applications. Thanks to use of specially designed pumps and control valves, the Load Sensing principle can be considered the most comprehensive means of creating a flexible hydraulic circuit that can adapt to the various conditions demanded by users.
The main feature of this principle is that the flow rate to the user is proportional to the spool position under any operating condition, regardless of the resistance encountered by the user (pressure) and the number of levers activated.
Therefore, with the LS systems, there is a specific correspondence between the position of the control lever and the movement speed of the user, cylinder or hydraulic motor. This feature is particularly useful in the hydraulic handling machine sector (excavators, cranes, loaders, agricultural and forestry machinery) in which each movement phase has specific sequences that the operator must control by using memorised movements.
Key benefits of the Walvoil DPC Series include:
Energy saving
Extension of part service life
Lower energy dissipation
Noise reduction
Available to create a single-pump circuit.
