DPC130

Walvoil _Load -Sensing Valve _DPC130

This sectional valve is normally used for mobile machinery, agricultural machines, cranes, drilling rigs and compactors. The spools have various hydraulic configurations: double‑acting, single acting, 4th position floating control and are pre‑set for different flow rates. The feedback‑based electro‑proportional control kit is equipped with on‑board electronics and can be interfaced with the CAN-bus system.

 

DPC38

Walvoil _Load -Sensing Valve _DPC38

Valve, available from 1 to 10 sections, is used for systems with fixed displacement pumps (open centre version) or Load‑Sensing variable displacement pumps (closed centre version). The service valves and intermediate sections avalibility, make DPC38 valve suitable for agricultural machines, drilling rigs, etc.

Full Flow Sharing - DPX Series
The new Load Sensing DPX series is designed based on a Flow Sharing concept providing for proportional flow distribution even at full capacity. Both available for fixed capacity (open center) pumps and variable (closed center) pumps.

DPX100

Walvoil _Load -Sensing Valve _DPX100

DPX100 modular valve has been designed for technical installations of latest generation on: mini-excavators, brush cutters, truck cranes, rubber tired excavators, and telescopic booms. Spools are designed for different capacities while a number of elements for specific functions, a range of proportional controls (also electric pilots) and auxiliary valves make our DPX100 a specially versatile and complete item.

 

 

DPX160

Walvoil _Load -Sensing Valve _DPX160 DPX160 modular valve is best suitable for advanced technical installations on: mini-excavators, crane trucks, telescopic booms and stacker cranes. Spools are designed for different capacities while a number of elements for specific functions, a range of proportional controls (also electric pilots) and auxiliary valves make our DPX160 a specially versatile and complete item.
