Product Description

GBV100 Proportional valve is a load sensitive and post-pressure compensated proportional valve. For post-pressure compensation valve, it can distribute flow proportionally for each working function. Because of the pressure comp-ensation, working flow is independent of load. All the proportional valves in this series have been load sensing and spring return. We can choose different cartridge unit for the main valve body to accomplishdifferent function. This series valve is building with modular design concept, system designer can choose differentmodule to accomplish various complicated system design. Valve spool can provide excellent flow characteristics and low flow force.

Functions

  • Inlet section matches with fixed displacement pump
  • Inlet section matches with variable displacement pump
  • Multiple control operations
  • Overload protections
  • Manual proportional valve can provide mechanical and friction detent
  • Main valve with float function

Options

  • Manually controlled proportional valve or mechanically controlled flow sharing proportional valve
  • Hydraulic pilot controlled proportional valve or hydraulic pilot controlled flow sharing proportional valve
  • Electrically controlled on/off valve or electrically controlled flow sharing proportional valve
  • Electro-hydraulic proportional valve or electro-hydraulic flow sharing proportional valve
