1 RELIEF VALVES Remote ontrol / Direct ype ilot Operated / Solenoid ontrolled Up to 5 Ma (3630 SI), 0 L /m in (06 U.S.GM) ub. E-00 Remote ontrol Relief Valves... age 3 his valve is used as a remote control valve for pilot operated type pressure control valves. Direct ype Relief Valves age 6 his valve is used in a hydraulic circuit to prevent damage due to over pressure and to adjust the maximum circuit pressure of small capacity. ilot Operated Relief Valves... age 9 hese valves protect the hydraulic system from excessive pressure, and can be used to maintain constant pressure in a hydraulic system. Remote control and unloading are permitted by using vent circuits. Low Noise ype ilot Operated Relief Valves... age 6 ilot operated relief valves here have been particularly develop-ed as low-noise types. Able to protect pumps and control valves against excessive pressures, they are used to control the pressure in the hydraulic system to a constant level. Remote control and unloading are permitted by using vent circuits. Solenoid ontrolled Relief Valves... age 0 hese valves are a combination of a pilot operated relief valve and a solenoid operated directional valve. iping between the two is eliminated as the solenoid valve is directly mounted on the relief valve and connected with the relief valve vent. ump pressure may be unloaded remotely by an electrical signal to the solenoid, or by connecting pilot relief valves to the solenoid valve ports. a "A" "B" b Low Noise ype Solenoid ontrolled Relief Valves... age 3 he low-noise solenoid controlled relief valve is a combination of a low-noise type pilot operated relief valve and a solenoid operated directional valve. It is used for no-load pump operation by using electric signals or, together with a remote control relief valve, for two or three pressure control of the hydraulic system. a "A" "B" b No.

2 RELIEF VALVES Remote ontrol / Direct ype ilot Operated / Solenoid ontrolled Instructions / Hydraulic Fluids AUION When making replacement of seals or solenoid assemblies, please do it carefully after reading through the relevant instructions in the Operator's Manual. Instructions o adjust the pressure, loosen the lock nut and turn the handle slowly clockwise for higher pressures or anti-clockwise for lower pressures. After adjustments, do not forget to tighten the lock nut. iping of the tank line should not be connected to any tank line of the other valves, but connected directly to the tank. Hydraulic Fluids Fluid ypes Any type of hydraulic fluids listed in the table below can be used. etroleum base oils Sy nthetic fluids Water containing fluids Use fluids equivalent to ISO VG 3 or VG 46. Use phosphate ester or poly ol ester fluid. When phosphate ester fluid is used, prefix "F-" to the model number because the special seals (fluororubber) are required to be used. Use water-gly col fluid. Note: For use with hy draulic fluids other than those listed above, please consult y our Yuken representatives in advance. Recommended Viscosity and Oil emperatures Viscosity ranging between 5-0 mm /s ( SSU). Oil temperatures between -5/+70 (5-58 F). Use hydraulic fluids which satisfy the recommended viscosity and oil temperatures given above. ontrol of ontamination Due caution must be paid to maintaining control over contamination of the hydraulic fluids which may otherwise lead to breakdowns and shorten the life of the valves. lease maintain the degree of contamination within NAS 638-Grade. Use 5 µm or finer line filter. No.

It prevents shock to the main circuit by gradually lowering the venting pressure in the shift from the setting pressure to unloading. Unloading pressures are the same as without a vent restrictor.
