FAQ
▔▔
What is the difference between a servo valve and a proportional valve?
Servo valves like the MOOG D661 provide significantly higher precision, faster response, and better repeatability compared with proportional valves. They are typically used in closed-loop control systems requiring extremely accurate motion control.
How do I select the correct D661 model?
The selection depends on several factors including flow requirement, operating pressure, electrical interface, and system control signal. It is recommended to confirm the original valve model number or consult a hydraulic specialist before purchasing.
