Pilot-Operated Proportional DC Valve Series D*1FH

Transcription

1 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 NG2 (CETOP5 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 D*1FH -57

4 Electronics Control system flow chart, valve electronics Wiring Enable input The power stage is activated via pin C (enable input). Arrangement of the potentiometers Supply voltage monitoring If the minimal supply voltage drops below, it is internally monitored and displayed via the status LED. Control monitoring A control error is indicated if there is an error in the control circuit of the valve. Spindle trimmer for zero point compensation Display is green Display off Normal operation Supply voltage is outside the permissible range of V LED Diagnostics for spool stroke Display is red Control error -60
