1 General information 1.1 Directional valve installation For the installation of the directional control valve on the equipment frame it is important to consider the following recommendations: - the valve can be assembled in any position but, in order to avoid deformations and spool sticking, the surface on which the product is mounted has to be flat; - before cabling pipelines, make sure that the pipeline hollows as well as fittings and seals are thoroughly clean; check also that the work ports are protected until the connection of the hoses. - during assembly and servicing operations, it is necessary to adopt clean procedures and work in an environment free of chips, swarf, dust and other possible source of pollution; - if the spools are connected to the equipment controls through linkages, make sure that they do not affect their operations; - before painting the valve, check that the work port plastic plugs are tightly in place. 1.2 Fittings In the interest of safety, only fittings with SRIGH HRED ENDS should be used (e.g. DIN3852). Fittings with ERED HRED ENDS (e.g. DIN 3852 form C) should never be used, as they can cause deformation and cracks in the valve body. Recommended tightening torque for work port fittings - Nm (lbft) Metric - ISO 261 With O-Ring seal (ISO 6149-1) With copper washer (ISO 9974-1) With rubber washer or steel (ISO 9974-1) S - ISO 228-1 With copper washer (ISO 1179-1) With rubber washer or steel (ISO 1179-1) UN-UNF - ISO 263 With O-Ring seal (ISO 11926-1) M18X1.5 40/29.5 40/29.5 35/25.8 3/8 S 40/29.5 35/25.8 SE8-3/4-16 UNF 40/29.5 Our warranty conditions will be not valid in case tapered fittings are used. he work port adaptors have to be fastened respecting the tightening torque values indicated in the following table (for different port types contact our Sales Dept.): Distributors information: HDM11S/3 Q shares the following components with HDS/HDM11S: - Spools - ositioners - djustable service port valves (nti-shock and anticavitation) - Single-double effect valve - Mechanical check valve (with HDM11S only) IMORN!: ightening torques depends on several different factors including lubrication, coating and surfaces finish. he fitting manufacturer shall be consulted. 1.3 Hydraulic fluid he main function of the fluid used in hydraulic systems is to transfer energy but it performs also other important functions: protect the components from corrosion, lubricate the directional valve moving parts, remove particles and heat from the system. In order to ensure proper operation and long life of the system it is important to choose the correct hydraulic fluid with proper additives. ucher Hydraulics recommends to use a mineral based oil responding to ISO 6743/4 requirements, only. he system should be operated only with hydraulic oil containing anti-foaming and antioxidant additives. efore using other types of fluid, please contact our Sales Dept, since they can cause serious damage to the directional valve components and jeopardize the correct function of the system. 1.4 Filtration In order to ensure proper operation and long life of the directional valve components it is extremely important to provide a proper and effective filtration of the hydraulic fluid. It is advisable to follow filter manufacturers instructions and recommendations. 3/24
he fineness of the filter should be selected in order to guarantee that a contamination level of 21/19/16 ISO 4406:1999 (NS 1638 class 10) is not exceeded. When the high reliability of the system is an important requirement a 10 μm nominal pressure filter must be used. In these cases it is also advisable to use a pressure filter with by-pass and indicator. For mechanical operated directional valves a <30 μm nominal return filter is adequate. he size of the return filters must suit the maximum return flow whereas the size of the pressure filters must suit the maximum pump flow. It is advisable to fit filters with pressure gauge or dirt indicator in order to make it possible to verify the filter condition. In order to obtain the best performance of the system we recommend to strictly follow the conditions advised here above, failing which warranty shall be void. 1.5 Directives and standards - tex: ttention: he equipment and protective systems of these catalogue RE NO intended for use in potentially explosive atmospheres that is to say where there is an explosive atmosphere referred to in rticle 2 of the Directive 99/92/EC and referred to rticle 1.3 of the Directive 94/9/EC - Machinery safety Hydraulic directional control valves are excluded by Directive 2006/42/EC - ISO 9001: 2000 ucher Hydraulics S.p.. is certified for research, development and production of directional control valves, power units, gear pumps and motors, electro pumps, cartridge valves and integrated manifolds for hydraulic applications. - ISO 14000 HRE is certified in Environmental Management System. 1.6 echnical specification: IMORN!: Specification and diagrams shown in this catalogue are measured with mineral oil having a viscosity of 23 mm 2 /s at 50 C Max inlet flow Max regulated flow Features Max continuous operating pressure supply port arallel circuit Max intermittent peak pressure work port / arallel circuit Max back pressure tank port Fluid temperature (with NR seals) 50 l/min (14 US gpm) 45 l/min (12 US gpm) 300 bar (4300 SI) 350 bar (5000 SI) 30 bar (430 SI) -20 C / +80 C (70 F / 180 F) Oil viscosity from 15 to 75 mm 2 /s ort threads size Max Spool leakage at 100 bar (1450 SI) temp 50 C (120 F) viscosity 23 mm 2 /s* Max Spool leakage at 125 bar (1800 SI) temp 50 C (120 F) viscosity 23 mm 2 /s* 3/8 S - M18x1.5 - SE8 12 cm 3 /min (0.7321 Cu.In./min) 14 cm 3 /min (0.854 Cu.In./min) (with UC Valves) max 3 cm 3 /min (0.183 Cu.In./min) (with RSM3 Valves) Number of spools 3 djustable direct operated relief valve (tamper-proof seal available on request) Load hold check valve in each section ntishock, anti-cavitation and combined valves Mechanical operated check valve For different operating conditions, please contact our Sales Dept.
