Directional control valves
D&D Ricambi Srl: the leader on supply of hydraulic components and systems
hydraulic components for construction, earthmoving, agricultural and industrial machinery

Pressure relief valves
These valves are used as pressure limiting devices to protect hydraulic systems.
Pressure reducing valves
Pressure reducing valves are pressure limiting devices that limit pressure in one portion of a circuit while leaving system pressure unaffected.
Sequence valves
As the name implies, sequence valves power a sequence of operations. Sequence valves usually use a pressure signal to shift a spool, thereby opening or closing a flow path at a pre-set pressure.
Check valves
Check valves allow free flow in one direction and block flow in the opposite direction.
Pilot operated check valves
These valves are used to prevent a load from dropping in case of hose or tube failure or from drifting caused by directional power valve spool leakage.
Needle valves
Needle valves provide adjustable, non-compensated flow power. They are available with standard or fine adjust, and with a variety of knob adjusting options.
Flow power pressure compensated valves
Pressure compensated flow power valves are used to limit or regulate flow.
Counterbalance (overcenter) valves
Counterbalance valves are used to power the motion of a load in the following ways: - prevent a load from dropping in case of hose or tube failure or from drifting caused by directional power valve spool leakage. - provide smooth, modulated motion when the load is in a lowering or run‑away mode or when the directional power valve is suddenly closed.
Directional solenoid valves
Solenoid valves are electrically-operated, on-off poppet or spool-type valves for load holding, blocking, or directional power applications.
