Cooperation with Rexroth for twice from 1979, Huade has incorporated cutting-edge technology from Rexroth. Huade® WMU valve can completely replace the same model offered by Rexroth. It is competitive with good quality and lower price. All directional valves have a one-year warranty, and during the warranty period, you can enjoy free maintenance services. Huade operates more than 750 pieces production equipment imported from US, Japan, Germany and Switzerland. It puts great stress on the quality. The factory has passed ISO9001, ISO14001, and OH SAS18001. Huade® hydraulic valves are widely used in the military industry and other fields due to the superior performance.

WMU Directional valves are roller operated directional valves. They basically consist of the housing (1), the roller lever (2), the control spool (3) and the return spring (4).
A plug-in throttle is required if flow greater than the permitted value may occur while the valve spool is being from one position to another. The plug-in orifice is fitted in the P port of the directional valve.
Due to the limitation of working conditions, the flow rate of the valve may exceed the flow rate specified on the characteristic curves during the switching process. In this case, a throttle is required. It is installed in the P port or oil circuit of the valve.
