概述：

hydraulic fluids to be u sed as well as the circuit construction 

which cannot be used by the conventional spool type directional valves 

because of too much internal leak of pressure oil.  

These are Solenoid Operated Directional Valves of No Leak Type developed 

The use of the low viscosity hydraulic fluids reduces the pressure loss 

which can a rise from the passage resistance of the hydraulic fluids, 

leading to the system energy saving.

with the aim of responding the demand of the a ge including energy saving.  

Because these valves are of no leak type they allow the low viscosity

技術(shù)參數：

there is no overlap, high response can be achieved.  

viscosity and oil temperatures given above.

Sheet type seal has been adopted and internal leak is greatly reduced.

Because the mounting surface conforms to ISO 4401-AB-03-4-A,

Oil temperatures between -15/+70°C (5 - 158°F).

Because these valves are of poppet type, 

Use hydraulic fluids which satisfy the recommended 

in combination with 01 Series Modular Valves.

there i s an interchangeability with the conventional valves.  

This makes it possible to use these valves 

Viscosity ranging between 15 - 400 mm /s (77 - 1800 SSU).  

At the same time, hydraulic lock is eliminated.
