wheel bulldozer Proportional Valves 

Introduction of GBV100 GBV100 Proportional valve is a load sensed and post pressure compensated proportional stackable valve. For post pressure compensation valve, it can distribute flow proportionally for each working function. Because of the pressure compensation, working flow is independent with load. All the proportional valves in this series have been load sensed, and spring centered. We can choose different plugin unit for the main valve body to accomplish different function. This series valve is building with modular design concept, system designer can choose different module to accomplish various complicate system design. Main valve spool can provide excellent flow characteristics and low flow force. This series can provide following functions to be selected ● lnlet section matches with fixed displacement pump ● lnlet section matches with variable displacement pump  ● Double control operations ● Overload protections ● Manual p…
