The model CDA4F15 multiple directional control valve is developed on the basis of similar advanced product abroad while considering the actual demand of domestic engineering vehicles. The valve features function completeness, fine performance, compact structure, small volume and weight light. In addition to the features of imported equipment, it has included such advantages as enlarging oil passageway, reduction in pressure loss, energy consumption and system heating.
The model CDA4F15 multiple directional control valve is of tandem structure. Users may select either number among the 10 pieces to combine oil circuits such as parallel, serialparallel, parallel and serialparallel ones. Its spool functions include O, OX, R, A, B and Y, R spool function is used for speed limiting when the fork truck gantry is leaning forward to avoid over speeding and cavitating. The OX spool function is used for attached tools in the actuating mechanism to ensure smooth and reliable action of attach tools. All functions have good inching features. Overload valves may be installed on all ports with their pressure set by users as required.
The inlet body of the model CDA4F15 multiple directional control valve is equipped with main relief valve for controlling main system pressure and steering relief valve for controlling steering system pressure. Its features are compact in structure, good in openingclosing characteristic and low in noise. Inside the inlet valve body there may be a flow stabilizing unit to provide stable flow to the steering system for its normal operation, which makes it possible that the single pump feeds oil to the steering system and working system at the same time. The valve is applicable to the hydraulic systems in fork trucks with its capacity under 3 tons, lightmediumsized loaders and other engineering and mining machinery. It can not only carry out integrated control over several actuating mechanism, but also be equipped with a single way flow stabilizing valve to provide stable flow to the steering system for reliable steering, an ideal substitute for imported products.
