Q is proportional to square root of corresponding ?p. ? Then, go to valve data sheet and select the closest spool to this value. Q nominal. = Q req. ?P real valve
And as an industry leader in the development of intelligent hydraulics, most Rexroth proportional and servo hydraulic valves have the option for integrated electronics or separate amplifiers. Bosch Rexroth There are low cost designs without spool feedback for manual and open loop control applications. These can be
For instance, proportional valves are operated by proportional solenoids whereas servo valves are operated by torque motors. The spools in proportional valves are almost entirely machine produced, while the spools in servo valves require a great deal of manual lapping and finishing. The clearances and tolerances in
Each energized actuator receives a pressure compensated flow. - No shuttle valve fitted. - Wet pin proportional tubes for DC coils, with push rod for mechanical override; nickel plated surface. - Manual override (push-button, screw type or lever) available as option. - Different plug-in connectors available: see ordering details

Standard directional proportional valves are perfect for many hydraulics applications. There are low cost designs without spool feedback for manual and open loop control applications. These can be direct or pilot operated. General purpose valves have better axis performance and accuracy, and Rexroth has implemented

All flow is blocked in and out of the pilot lines to shift the main spool. When the main valve is in the center position, the main spool. LVDT should send back 0 volts as well. Nulling and centering of the valve is discussed in the valve amplifier section of this manual. Page 22. Troubleshooting Proportional Valves. Bosch Valves
