RELIEF VALVES Remote Control / Direct Type Pilot Operated / Solenoid Controlled

PRESSURE CONTROLS

Up to 25 M Pa (3630 PSI), 400 L /m in (106 U.S.GPM ) Remote Control Relief Valves ..................... Page 3

C

This valve is used as a remote control valve for pilot operated type pressure control valves.

Direct Type Relief Valves ............................ Page 6 This valve is used in a hydraulic circuit to prevent damage due to over pressure and to adjust the maximum circuit pressure of small capacity.

Pilot Operated Relief Valves ....................... Page 9 These 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 Type Pilot Operated Relief Valves ....................... Page 16 Pilot 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 Controlled Relief Valves .............. Page 20 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 to the solenoid, or by connecting pilot relief valves to the solenoid valve ports.

Low Noise Type Solenoid Controlled Relief Valves .............. Page 31 The 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.

RELIEF VALVES Remote Control / Direct Type Pilot Operated / Solenoid Controlled Instructions / Hydraulic Fluids

PRESSURE CONTROLS

CAUTION When making replacement of seals or solenoid assemblies, please do it carefully after reading through the relevant instructions in the Operator's Manual.

Instructions To 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 Fluids Fluid Types Any type of hydraulic fluids listed in the table below can be used. P etroleum base oils

Use fluids equivalent to ISO VG 32 or VG 46.

Sy nthetic fluids

Use 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 fluids

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 Temperatures Viscosity 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 Contamination 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. Please maintain the degree of contamination within NAS 1638-Grade 12. Use 25 µm or finer line filter.

Sub-plates are available. Specify the sub-plate m odel num ber from the table above. W hen sub-plates are not used, the m ounting surface should have a good m a-chined finish.

Instructions If a remote control relief valve is used in the vent circuit, see page 3. In addition, if the internal volume of the vent line 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. Use models numbered 03 and 06 with a flow rate above 8 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 the other as an outlet or the valve can be used by plugging one of the pressure ports.

Instructions If a remote control relief valve is used in the vent circuit, see page 3. In addition, if the internal volume of the vent line 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. Use models numbered 03 and 06 with a flow rate above 5 L/min (1.3 U.S. GPM) and model 10 with 8 L/min (2.1 U.S. GPM).

Sub-plates are available. Specify the sub-plate m odel num ber from the table above. W hen sub-plates are not used, the m ounting surface should have a good m achined finish. The sub-plates are those for pilot operated relief valves. For dim ensions, see page 13.

Option Models with vent restrictor The type with a vent restrictor has a vent restrictor in vent types 2B3A and 2B3B added between a relief valve and a solenoid operated directional valve. If prevents shock to the main circuit by gradually lowering the venting pressure in the shift from the set pressure to unloading. Unloading pressure are the same as without a vent restrictor.

Instructions If a remote control relief valve is used in the vent circuit, see page 3. In addition, if the internal volume of the vent line 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. Use models numbered 03 and 06 with a flow rate above 8 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 the other as an outlet or the valve can be used by plugging one of the pressure ports.

Interchangeability in Installation betw een Old and New Design. Design 47 valve is one on which DSG-01,design 60 is mounted as a pilot valve. It is interchangeable with old design (design 46) with respect to specifications, exterior shape and mounting dimensions.

Option Models with vent restrictor The type with a vent restrictor has a vent restrictor in vent types 2B3A and 2B3B added between a relief valve and a solenoid operated directional valve. 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.

Instructions If a remote control relief valve is used in the vent circuit, see page 3. In addition, if the internal volume of the vent line 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. Use models numbered 03 and 06 with a flow rate above 5 L/min (1.3 U.S. GPM) and model 10 with 8 L/min (2.1 U.S. GPM).
