Product Desciption
Application:
Numerous integrated valve features in addition to countless configuration options make D4 highly flexible and easilyadaptable to the widest applications range. The valve is available with manual, direct electric, hydraulic remote, pneumatic, electrohydraulic and electropneumatic controls. Special versions for LS variable pumps can be realised on request. Suitable for applications including cranes and aerial platforms, compactors, hook and skip loaders, drlling machines, forklifts, wheel loaders, backhoe loaders and excavators max 7 t.
Following features are available on D4 family:
Direct electric control push push type.
Special auxiliary valve for Single acting/Double acting choice (tractor application).
Special inlet with Priority Steer function integrated for LS and CA systems (Fork lift trucks, Telehandler, Loaders).
Special circuit to regulate reduced flow on HPCO connection (Truck mounted cranes, stabilizers circuits).
Special inlet section for parallel valves connection (suitable for forest applications). .
Boom Priority function (Wheel loaders)
Potentiometer and microswitch kits and Overcenter spool (Fork lift trucks).
Standard working condition:
All information and diagrams in this catalogue refer to a mineral base oil VG46 at 50%C temperature (32 cSt kinematic viscosity)
