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 control 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.
Automatic cut-off valve
They allow the pump unload when the setting pressure is reached; they permit also the maintenance of the pressure using an accumulator.
Regenerative valve
They allow the connection between rod and base of an hydraulic cylinder. They permit the movement reversal using a pressure signal.
High/low pressure cut-out valve
In a system powered by two pumps, the valve allows operations with a fast/slow sequence.
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 control valve spool leakage
Flow control pressure non-compensated valves
Throttle valves allow for adjustable and non-compensated control of the flow rate. They are available with standard or fine adjustment, with different control devices.
Flow control pressure compensated valves
Pressure compensated flow control valves are used to limit or regulate flow.
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 control valve spool leakage.
Directional solenoid valves
Solenoid valves are electrically-operated, on-off poppet or spool-type valves for load holding, blocking, or directional control applications.
Automatic reversing valves
These valves are used to switch automatically the oil flow direction by using two type of control: mechanical and pressure increase.
