 Limit the pressure drop between the valve and the accumulator in an accumulator circuit

 below 10% of the cut-out pressure.

Limit the drain port back pressure below 2% of the cut-out pressure.  

Recommended Viscosity and Oil Temperatures  2  Viscosity ranging between 15 - 400 mm /s (77 - 1800 SSU)

when the system pressure reaches to a cut out pressure (adjusted maximum),

 the valve acts to divert the pump delivery to the reservoir a t low pressure, 

the hydraulic fluids which may otherwise lead to breakdowns and shorten 

the life of the valves.  Please maintain the degree of contamination within NAS 1638-Grade 

12.  Use 25 µm or finer line filter.  Control of Contamination

To adjust the pressure, loosen the lock nut and turn the pressure adjustment

 handle slowly clockwise for higher p ressures or anti-clockwise for lower pressures. 

 After adjustments, do not forget to tighten the lock nut. 

Oil temperatures between -15/+70°C (5 - 158°F).  Use hydraulic fluids which satisfy 

the recommended viscosity and oil temperatures given above

pump with the same manner as described above during load operation of the small volume pump.

Fluid Types Hydraulic Fluids Any type of hydraulic fluids listed in the table below can be used.

Note: For use with hydraulic fluids other than those listed above, 

otherwise not only will the valve fail to operate p roperly 

but also the line pressure will rise infinitely.  Extend the end of the drain pipe into fluid.

These valves are used to operate the pumps with minimum load in accumulator circuits

or in high-low pump circuits.  In accumulator circuits, 

thus the pump is unloaded automatically.  When the accumulator pressure drops to the cut in pressure 

(refer to characteristic chart on page 5), the valve directs the pump delivery to the accumulator 

and hydraulic system.  An integral check valve prevents reverse flow through the valve from the accumulator. 

 In high-low pump circuits, the valve acts to unload the large volume 

Instructions Take care not to neglect connecting the drain pipe to the tank;

please consult your Yuken representatives in advance. Recommended Viscosity and Oil Temperatures
