Pilot Operated Proportional DC Valve Series D*1FH

Catalogue HY11-3500/UK

Characteristics The pilot operated proportional DC valves series of the D*1FH series are high-performance valves with electronic spool position feedback. These valves are available in sizes NG10 to NG32 (CETOP05 to CETOP10). Typical applications are: High precision and reproducible adjustment of flow rates, applications in rapid / creep speed with spool position monitoring for presses and dynamic position and p/Q closed loop systems. Technical features • Very low hysteresis • Zero lap and overlap spool design available • High dynamics • Spool position feedback • Center position monitoring optional • D31FH – NG 10 (CETOP05) • D41FH – NG 16 (CETOP07) • D81/91FH – NG 25 (CETOP08) • D111FH – NG 32 (CETOP10)
