Product Overview

Cooperation experiences with Rexroth from 1979. Huade® remote control relief valve DBT has an affordable price. It is more advanced in technology and more durable than the similar products in this line. Huade Hydraulic puts great stress on the quality. The factory operates more than 750 pieces advanced production equipment imported from all over the world to ensure the quality of hydraulic valves. All pressure valves will undergo rigorous testing before leaving the factory. The factory has passed ISO9001, ISO14001 and OH SAS18001. Huade® is an outstanding brand in Chinese hydraulic industry. The series of pressure control valves are widely used in marine hydraulic system and other fields due to the superior performance.

Key Features

  • long distance remote control
  • subplate mounting
  • three adjustment elements:
  • Rotary knob
  • Hex. head screw with protective cap
  • Lockable rotary knob with scale
  • Types DBT and DBWT remote control pressure valves are pilot operated pressure relief valves.
  • Type DBT consist mainly of the main valve (1), main spool (2), valve seat (3), and adjustment (6)
  • The pressure of system acts on the spool(2) via orifice. If the pressure exceeds the valve set at the spring, the pressure fluid drain to tank from port T(or drain external).
  • Structure and symbols of pressure relief valve DBT
  • The fluid must be filtered. Minimum filter fineness is 20 ㎛.
  • The tank must be sealing up and an air filter must be installed on air entrance.
  • Products without subplate when leaving factory.
  • Valve fixing screws must be high intensity level (class 10.9). Please select and use,them according to the parameter listed in the sample book.
  • Roughness of surface linked with the valve is required surface roughness is 0.8.
  • Surface finish of mating piece is required to 0.01/100mm.
