Anti-cavitation valves, maximum pressure relief valves, priority valves and “load sensing” priority valves built in the following series of gear pumps and motors: POLARIS, WHISPER, KAPPA, New KAPPA Compact
Reduced overall dimensions
Simplified plant design
Wide choices of ports position
Pressure relief valves
These valves are used for the protection of hydraulic systems from overpressures.
Pressure reducing valves
The pressure reducing valves are devices which limit the pressure in a portion of the hydraulic circuit maintaining the pressure of the system unchanged.
As the name suggests, the sequence valves are used to command a sequence of operations. Typically use a pressure signal to move a cursor, by opening and closing the flow to a pre-set pressure.
Automatic shutdown valves
Allow the unloading of the pump to the achievement of the set pressure and subsequently allow the maintenance of the pressure itself through the use of an accumulator.
Circuit regenerative valves
Allow the connection between piston rod and bottom of a hydraulic cylinder (regenerative circuit). Through a pressure signal allow the reversal of the movement.
High-low pressure exclusion valves
In a system powered by two pumps, the valve permits the application of drives with fast-slow sequence.
The unidirectional valves allow free movement in one direction and block flow in the opposite direction.
Piloted block valves
Are employed in the prevention of the fall of the load, due to breakage of pipes and fittings or caused by excessive leakage of the distributor.
Non-compensated flow control valves
The throttle valves allow adjustable and not compensated control of flow rate. Are available with fine or standard regulation, with different control devices.
Compensated flow control valves
They are used to adjust or reduce a flow.
Motion control Valves
The balancing valves are used to control the movement of the load in the following ways: - prevent the fall of the load, due to breakage of pipes and fittings or caused by excessive leakage of the distributor. - allow a drive-modulated and free from jamming when the load is being run down or run-away or when the distributor is suddenly excluded.
Directional solenoid valves
The solenoid valves are electro-driven, ON / OFF cone or cursor, for the maintenance of the load, blocking, for applications of directional control.
These valves are used to automatically reverse the direction of flow: are available with mechanical or pressure increase control.
