Product Overview

WMM 6 valves can completely replace can replace the same model of Rexroth® due to  two long-term cooperation experiences between Huade and Rexroth. The price of Huade® WMM 6 is more reasonable. It is competitive with good quality and lower price. Huade operates more than 750 pieces production equipment imported from US, Japan, Germany and Switzerland. It puts great stress on the quality with a very strict testing system. The factory has passed ISO9001, ISO14001, and OH SAS18001. It is a a reliable national brand in China. Huade's hydraulic valves are widely used in the military industry and other fields due to the superior performance.

Key Features

  • Direct actuated directional spool valve with hand lever
  • With spring return or detent, optional
  • For subplate mounting
  • Small size, large flow capacity and good reliability
  • Porting pattern to Din 24 340 form A, ISO 4401 and CETOP - RP 121H

Industrial Applications

  • Directional valve type WMM 6 can be used together with other sandwich valves of the same size. It is widely used in construction machinery, chemical machinery, light industrial machinery, locomotives and other industries.
  • The WMM 6 directional valves are hand lever actuated directional spool valves.They control the start, stop and direction of a flow.
  • The directional valves basically comprise of a housing①, hand lever②, control pool ③, as well as one or two return springs④. In the unoperated condition the control spool③ is held in the neutral or its initial position by the return springs ④. The control spool③ is actuated via the hand lever ②, this acts via a joint and the pin⑤ directly onto the control spool ③. The spool is thereby moved out of its rest position into its required switched position. After the hand lever ② has been returned to the switched position zero, the spool ③ is returned to the neutral position via the return springs ④.
  • Type 4WMM../F.. (with detent)
  • These valves are either 2 or 3 position directional control valves which are fitted with a detent, which operates in all of the switched positions
  • Cutaway view of type WMM 6
  • Cartridge throttle
