Direct Operated Proportional DC Valve Series D1FP*S
Catalogue HY11-3500/UK
Characteristics The direct operated control valve D1FP*S of the nominal size 04 (ISO 10372) shows extremly high dynamics combined with maximum flow. The valve mounting pattern is designed to replace servovalves of size 04 (ISO 10372) with the D1FP*S. Driven by the new patented VCD® technology the D1FP*S shows all advantages of the DFplus® series as robustness, high dynamics and no flow limit up to 350 bar. Additional features are low leakage and a defined spool position in case of power supply breakdown. Maintenance and contamination restrictions correspond to common solenoid driven valves and pilot supply is not required. All common input signals are available.
