Flow control valve
D680 series MOOG

Pilot-Operated Proportional Valves for Analog Signals D680 Series

Optimized design of valve bodies for high rated flow
Reduced pilot flow due to 2-stage valve with direct-operated pilot valve
Low range of minimum pilot pressure required
Excellent dynamic response due to high natural frequency of pilot stage
Different fail-safe options available allowing the best fit to application
