Key Features

  • long distance remote control
  • subplate mounting
  • three adjustment elements:
  • Rotary knob
  • Hex. head screw with protective cap
  • Lockable rotary knob with scale

Industrial Applications

  • Type DBWT is apply to remote control the pressure of system and drain by actuating the electrically operated valve.
  • Type DBWT remote control pressure valves are pilot operated pressure relief valves.
  • Type DBWT consist mainly of the main valve (1), main spool(2), valve seat (3), electrically operated valve (5), and adjustment (6)
  • Structure and symbols of pressure relief valve DBWT
  • 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, if need them, please ordering specially.
  • 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.
