Page 3CThis valve is used as a remote control valve for pilot operated typepressure control valves.Direct Type Relief Valves . Page 6This valve is used in a hydraulic circuit to prevent damage due toover pressure and to adjust the maximum circuit pressure of smallcapacity.Pilot Operated Relief Valves . Page 9These valves protect the hydraulic system from excessivepressure, and can be used to maintain constant pressure in ahydraulic system. Remote control and unloading are permitted byusing vent circuits.Low Noise TypePilot Operated Relief Valves . Page 16Pilot operated relief valves here have been particularly develop-edas low-noise types. Able to protect pumps and control valvesagainst excessive pressures, they are used to control the pressurein the hydraulic system to a constant level. Remote control andunloading are permitted by using vent circuits.Solenoid Controlled Relief Valves . Page 20These valves are a combination of a pilot operated relief valveand a solenoid operated directional valve. Piping between thetwo is eliminated as the solenoid valve is directly mounted onthe relief valve and connected with the relief valve vent. Pumppressure may be unloaded remotely by an electrical signal to thesolenoid, or by connecting pilot relief valves to the solenoidvalve ports."A"Low Noise TypeSolenoid Controlled Relief Valves . Page 31The low-noise solenoid controlled relief valve is a combinationof a low-noise type pilot operated relief valve and a solenoidoperated directional valve. It is used for no-load pump operationby using electric signals or, together with a remote control reliefvalve, for two or three pressure control of the hydraulic system."B"ba"A"a"B"bNo.1
RELIEF VALVESRemote Control / Direct TypePilot Operated / Solenoid ControlledInstructions / Hydraulic FluidsPRESSURECONTROLSCAUTIONWhen making replacement of seals or solenoidassemblies, please do it carefully after readingthrough the relevant instructions in the Operator'sManual.InstructionsTo 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.Piping of the tank line should not be connected to any tank line of the other valves, but connected directly to the tank.Hydraulic FluidsFluid TypesAny type of hydraulic fluids listed in the table below can be used.P etroleum base oilsUse fluids equivalent to ISO VG 32 or VG 46.Sy nthetic fluidsUse phosphate ester or poly ol ester fluid. W hen phosphate ester fluid is used,prefix "F-" to the m odel num ber because the special seals (fluororubber) are required to be used.W ater containing fluidsUse 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 TemperaturesViscosity ranging between 15 - 400 mm2/s (77 - 1800 SSU).Oil temperatures between -15/ 70 C (5 - 158 F).Use hydraulic fluids which satisfy the recommended viscosity and oil temperatures given above.Control of ContaminationDue caution must be paid to maintaining control over contamination of the hydraulic fluids which mayotherwise lead to breakdowns and shorten the life of the valves. Please maintain the degree of contamination withinNAS 1638-Grade 12. Use 25 µm or finer line filter.No.2

W hen sub-plates are not used, the m ounting surface shouldhave a good m a-chined finish.InstructionsIf a remote control relief valve is used in the vent circuit, see page 3. In addition, if the internal volume of the ventline is too large, chattering is likely to occur. Thus, as far as possible reduce the inside Dia. and the length of the pipe.Pressure is limited by collars fitted. If a working pressure cannot be attained, remove some collars. One collar isequivalent to 10 MPa (1450 PSI).With a small flow, the setting pressure may be unstable. Use models numbered 03 and 06 with a flow rate above8 L/min (2.1 U.S. GPM) and model 10 with 15 L/min (4.0 U.S. GPM).There are two threaded connection pressure ports. They can be connected each other in-line; one as inlet and theother as an outlet or the valve can be used by plugging one of the pressure ports.No.10

In addition, if the internal volume of the ventline is too large, chattering is likely to occur. Thus, as far as possible reduce the inside Dia. and the length of the pipe.Pressure is limited by collars fitted. If a working pressure cannot be attained, remove some collars. One collar is equivalent to 10 MPa (1450 PSI).With a small flow, the setting pressure may be unstable.

Solenoid
Solenoid Controlled Relief Valves These valves are a combination of a pilot operated relief valve and a solenoid operated directional valve. Piping between the two is eliminated as the solenoid valve is directly mounted on the relief valve and connected with the relief valve vent. Pump pressure may be unloaded remotely by an electrical signal .
