Frequently Asked Questions
How do MOOG servo valves work?
Most MOOG servo valves are two-stage valves. In the first stage, an electrical signal is sent to a torque motor, which moves a flapper between two nozzles, creating a pressure differential. This pressure difference acts on a spool (the second stage), moving it to control the main hydraulic flow to the load. The valve may use mechanical feedback (e.g., a spring) or an electrical feedback system (LVDT sensor) to ensure the spool position accurately corresponds to the input command signal.
What are the main advantages of MOOG Servo Valves?
High-Precision Control: They offer exceptional control accuracy, which can reach about 0.1%, suitable for demanding appliions.
High Dynamic Performance: They feature fast response times, often in the millisecond range, allowing for high-speed and high-precision control.
High Reliability and Stability: Designed with advanced technology and materials for stable long-term operation, even in harsh environments.
Variety of Designs: Available in various series, including standard two-stage, high-performance two-stage and three-stage, and direct-drive valves (DDV) to meet different performance needs.
Fail-Safe Functionality: Some models include a fail-safe feature that moves the valve to a safe position in case of a power failure or system fault.
What are the main series of MOOG Servo Valves?
MOOG offers a comprehensive range of servo valves. Some prominent series include:
G761 Series: A popular two-stage flow control valve with mechanical feedback. Known for fast response and robustness, it is widely used in various industrial appliions.
D630 Series (e.g., D634, D636, D637): These often feature direct drive by a linear force motor (DDV) or advanced control. The D636/D637 series, for example, comes with a fieldbus interface and integrated digital electronics for high flexibility.
D660, D661, D662 Series: Classic two-stage servo valves with a wide range of industrial uses.
72 Series: Standard response two-stage valves with a field-replaceable pilot valve filter and the option for external pilot pressure control.
