Servo and Proportional Control Valves with Integrated Electronics
1. INTRODUCTION
This manual provides instructions and procedures necessary
to install, operate and troubleshoot the Moog D661 Series Servo and Propor-
tional Control Valves.
Series Models
Series G
Servovalve with nozzle-flapper or ServoJet
stage, spool in bushing, without additional mechanical
feedback
Series S

mechanical feedback
Series H
Servovalve configured like version S, but with improved
performance (high response)
Series P...A/B
Proportional valve with ServoJet
without additional mechanical feedback
Series P...F/G
Proportional valve configured like version P...A/B, but
with nozzle flapper pilot stage and additional mechanical
feedback
2. OPERATION
General
The Servovalves D661-G, S and H Series and the Proportional Flow
Control Valves D661-P Series are throttle valves for 2-, 3- and 4-way
applications. With proportional flow control valves, 5-way applications are also
possible. These valves are suitable for electrohydraulic position, velocitiy,
pressure or force control systems with high dynamic response requirements.
D661-G, S and H
The spool of the main stage is driven by a nozzle flapper or ServoJet
pilot stage, optional with or without additional mechanical feedback (nozzle
flapper only).
With versions D661-S and H in case of an electrical supply failure
the spool is moved into a preferred position by action of an additional
mechanical feedback.
CAUTION
DISASSEMBLY, MAINTENANCE, OR REPAIR OTHER THAN IN ACCORDANCE WITH THE
INSTRUCTIONS HEREIN OR OTHER SPECIFIC WRITTEN DIRECTIONS FROM MOOG WILL
INVALIDATE MOOG'S OBLIGATIONS UNDER ITS WARRANTY.
