Product Overview

Huade is a Chinese well-known state-owned enterprise specializing in hydraulic system. Huade had two long-term cooperation experiences with Rexroth from 1979. Huade® WMR valve is an affordable alternative to Rexroth's same series. This directional valve enjoys free maintenance service within the one-year warranty period. Huade puts great stress on the quality. The factory has passed ISO9001, ISO14001, and OH SAS18001. Huade® hydraulic valves are widely used in engineering and construction machinery, metallurgy, machine tools, environmental protection, shipbuilding, aerospace, rail transit, petroleum and petrochemical, military industry and other fields. It is a reliable brand in China.

In symbols A and B,the T port must be used as a drain connection  if the operating pressure is above the pressure permitted at the T port

for symbol Q, 6% of nominal cross section

for symbol W, 3% of nominal cross section

Mineral oils(for NBR seal) or phosphate ester(for FPM seal)

Key Features

  • Direct operated directional spool valve with adjustable roller operation
  • Roller lever assembly may be stepped in 90°
  • Radial forces absorb reliably (up to 30°)
  • 19 kinds standard spool function
  • Directional valves type WMR 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.
  • Cutaway view of WMR 6
  • Cartridge throttle
