GBV200 Proportional valve is a load sensitive and post-pressure compensated proportional valve. For post-pressure compensation valve, it can distribute flow proportionally. Because of the pressure compensation, 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 accomplish different function.This series valve is building with modular design concept, system designer can choose different module to accomplish various complicated system design. Valve spool can provide excellent flow characteristics and low flow force.
