With the continuous development and progress of construction machinery, high-pressure and high-flow load sensitive engineering valves have been widely used in the field of construction machinery, and the competition in the domestic and foreign markets is very fierce. The HD-MWVL25 series multi-way valve and HD-MWVL36 series multi-way valve launched by Huade Hydraulics are widely used in crawler cranes, truck cranes, coal drilling rigs, rotary drilling rigs, special drilling rigs and other mobile machinery fields.
HD-MWVL25 series multi-way valve has launched HD-5MWVL25-2X/five-way integral structure on the basis of sheet structure and triple integral structure, and HD-MWVL36 series has launched HD-6MWVL36-2X/six-way integral multi-way valve on the basis of disc structure. HD-5MWVL25-2X/five-gang integral multi-way valve and HD-6MWVL36-2X/six-gang integral multi-way valve have the functional characteristics of disc products, the integral design makes the structure more compact, the function is further integrated, the internal casting oil channel and flow field are further optimized, and the pressure loss is further reduced. In addition, the integral multi-way valve can easily increase the number of reversing connections and expand the function through the standard extended connection surface, and the electronic and hydraulic control forms are optional.
