General InformationThe CV 112 Special Loader Valve has been designed to fit all loaders with a flow rate up to 50 l/min or 12GPM and a maximum pressure of 320 bar or 4600 psi.The CV 112 can be operated both in loaders with either open Center systems or LS systems depending onits build configuration.The CV 112 Special Loader Valve offers the loader builder a number of key features to enhance the loaderperformance such as :• Exceptional Low Spool leakage rates (less than 2 cc/min or 0.122 inch 3 /min).• Load Check valves on each spool.• Direct Acting Main Relief Valve for fast response to system over pressure.• Float Function for the lowering circuit.• Regen Function for the tilt circuit.• DIRECT MOUNTED JOYSTICK for both float and regen.• Cable Control option.• Power Beyond option.• BSP and SAE Threads are standard but also Metric and NPTF can be offered upon request.Directional Control Valve 3Series CV 112
