Technical Data Performance Specs. Ordering Information MOOG SERVO-PROPORTIONAL CONTROL VALVES For over 25 years, Moog has manufactured proportional control valves with integrated electronics. During this time more than 150,000 valves have been delivered. These proportional control valves have been proven to provide reliable control of injection and blow molding equipment, die casting machines, presses, heavy industry equipment, paper and lumber processing and other applications. ¢ The valve now places an optional enable signal at the operator’s disposal. If no enable signal is available,...

FEATURES & BENEFITS Flexible Design Elements Optimize the Valve to Your Application The D661-G….A Series Proportional Control Valves are a twostage design. The spool motion of the main stage is produced by a single-stage pilot valve. Two-stage proportional valves are mainly used when low threshold and good dynamic response with small signals are required. By combining a fast first stage, a suitable spool drive area and integrated electronics, an optimum proportional valve can be offered. Highest Flow Capability for High Velocity Applications The D661-G….A Series valves offer the highest...

TECHNICAL DATA Operating Principle of the ServoJet® Pilot Stage The ServoJet® pilot stage consists mainly of the torque motor, jet pipe and receiver. A current through the coil displaces the jet pipe from neutral. This displacement combined with the special shape of the nozzle directs a focused fluid jet more into one receiver opening than the other. The jet now produces a pressure difference in the control ports.This pressure difference results in a pilot flow which in turn causes a spool displacement. The pilot stage drain is through the annular area around the nozzle to tank. Hydraulic...

TECHNICAL DATA INSTALLATION DIAGRAM The mounting manifold must conform to ISO 4401-05-05-0-94. Attention: Manifold length min. 100 mm. Note O-ring counterbore dia. of X and Y ports. For valves in 4-way version with QN > 160 l/min, the non-standard 2nd return port T2 must be used. For maximum flow, the manifold ports P, T, A and B should have 0.45 in [11.5] dia (deviation from standard). counterbore Mounting surface needs to be flat within .0005 in [0.01] over a distance of 3.94 in [100]. Average surface finish value, Ra, better than 32. SPARE PARTS AND ACCESSORIES O-rings (included in...

VALVE ELECTRONICS WITH 24 VOLT SUPPLY Command signal 0 to ±10 mA floating, Valves with current command input The spool stroke of the valve is proportional to ID = –IE. 100% valve opening P ± A and B ± T is achieved at ID = +10 mA. At 0 mA command the spool is in its center position. The input pins D and E are inverting. Either pin D or E is used according to the required operating direction. The other pin is connected to signal common at cabinet side. Command signal 0 to ±10 V, Valves with voltage command input The spool stroke of the valve is proportional to (UD – UE). 100% valve opening P...
