Oct 13 2008 Pressure compensated flow control valves are often used in hydraulic systems when accurate speed control is required under varying supply or load pressures The basic structure of the pressure compensated flow control valve is by incorporating a compensating spool to maintain a constant pressure drop across the metering orifice.
The pressure differential is determined by the pressure compensator spring and depending on the selected design it ranges between 8 and 25 bar The combination of a proportional directional valve with a pressure compensator ZDC and Rexroth SCA r esults in the effect of a flow control valve for 2 directions.
