1.0 General Information Operating Principle: CLS180 is a load sensing and flow sharing directional control valve. The flow sharing technology applied to the standard load sensing system characterizes the new CLS180. The valve is completely pressure compensated and guarantees great controllability to all actuations, making work port flow dependent only on the metering area (spool position). When flow saturation occurs the system reacts by implementing an equal reduction of pressure margin across all spools, generating a proportional reduction of work port flow. 2 1 Multi-section: When two or more sections are actuated only one, characterized by the highest pressure (dominant), is involved in the load sense (LS) signal transmission. It works as briefly described in the previous paragraph. The other functions (slaves) become directly dependent on it. The common LS line transfers the information coming from the dominant local compensator to all dependent compensators. Driven by the LS signal, the unbalanced slave compensators activate the pressure compensation creating an artificial pressure drop able to keep pressure margin nominally the same on all the spools. Work port flow becomes only a function of the metering area making the system totally load independent. Flow Sharing function: When saturation occurs the total amount of flow required by actuations is higher than the maximum pump flow rate. When this occurs, system is no longer able to hold nominal margin pressure. The actual margin pressure reduces according to real flow demand. Since all the local compensators have the same LS signal and the same pressure drop is applied to different metering areas, then work port flows are reduced proportionally in order to keep all actuations completely under control. Pump compensator Legend: 1 Inlet line (high pressure) 2 Metering notches 3 Load sensing line 4 Local compensator 5 Metering spool 4 Single section: Coming from the common inlet the main flow, passing across the metering area, reaches the local compensator. Depending on the main spool chosen, the metering area controls the total amount of flow to the work port based on the margin pressures. The load sensing signal is picked up downstream of the local compensator which feeds the common load sensing line. When a single section is actuated, the local compensator fully opens to the left side, reaching its complete balanced position. The control of the LS system is made by the inlet compensator for fixed displacement pump or pump compensator for variable displacement pump. 3 5 T P M LS signal Dump valve LS signal Relief valve LS Full flow relief valve A1 B1 A2 B2 A3 B3 A4 B4 Post local compensator D1 Internal press. reducing valve D2 (drain line) R 4 EATON CLS180 Proportional Load Sensing Mobile Valve E-VLVM-TT003-E July 2018

Remove actuator end cap assemblies. Remove spool from the section body from the spring end side. It will be observed that the spring sub-assembly will be in assembled condition to the spool. Preferably, it is best to mount the spool into a collet in order to secure it. The spool can also be placed inside a rubber hose and clamped into a vise to avoid damage to the spool diameter. Remove the spool joints from both ends of the spool. It may take considerable torque to overcome the loctite while removing the spool joints. Reinstall the spool joint with the spring assembly onto the opposite ends of the spool. Re-install the spool into the work section. Please note that the spool orientation should be the same and only the spool joint orientation will be swapped. Then reassemble the spring cap actuations by installing them on the opposite section ends. Care must be taken to ensure all cap o-rings are properly installed before attaching the cap to the section housing. Ensure the override pawl engages the spool clevis. Similar procedure can be followed to change from RH build to LH build. EATON CLS180 Proportional Load Sensing Mobile Valve E-VLVM-TT003-E July 2018 31
