MOOG servo valves regulate the required pressure using pressure reducing valves and the required flow rate using throttle valves. This traditional pneumatic control system requires multiple pressure reducing valves, throttle valves, and directional valves to achieve multiple output forces and multiple movement speeds. This not only increases the number of components, raising costs and complicating the system structure, but also requires many components to be manually adjusted in advance. Electro-proportional valve control is a continuous control method, characterized by output varying with input, and a certain proportional relationship exists between the output and input. Proportional control can be divided into open-loop control and closed-loop control.

MOOG Servo Valve Working Principle
The MOOG servo valve consists of a permanent magnet torque motor, nozzle, baffle, valve core, valve sleeve, and control chamber. When current is applied to the input coil of the servo valve, the baffle moves to the right, strengthening the throttling effect of the right nozzle, reducing the flow rate, and increasing the back pressure on the right side; simultaneously, it reduces the throttling effect of the left nozzle, increasing the flow rate, and decreasing the back pressure on the left side. The forces at both ends of the valve core become unbalanced, causing the valve core to move to the left. High-pressure oil flows from S to C2, delivering it to the load. The load return oil flows through C1 and through the return port into the oil tank. The displacement of the valve core is proportional to the input current of the torque motor, and the hydraulic pressure acting on the valve core is balanced by the spring force. Therefore, in a balanced state, the differential current of the torque motor is proportional to the displacement of the valve core. If the input current is reversed, the flow rate is also reversed. The table shows the classification of servo valves.

In 1988, Robert T. Brady, president of the aircraft division of MOOG Corporation, was appointed as CEO. Sales reached $282 million in 1989. The company established operations in India in the mid-1990s. Our major acquisition was the purchase of Allied Signal's aircraft business in Torrance, California. By the end of 1999, the company's revenue exceeded $630 million.
In 2001, MOOG won a $50 million contract to refurbish the Space Shuttle and moved from the American Stock Exchange to the New York Stock Exchange. We are the designer and supplier of flight control systems for Lockheed's F-35 fighter jet and a major supplier of flight control components for Boeing's 787 "Dreamliner" program.
In 2004, the company's revenue surpassed $900 million, and we completed another major acquisition, acquiring Litton Poly-Scientific and renaming it MOOG Components Group. The company's annual sales exceeded $1 billion.
MOOG Founder
MOOG Founder: Bill Moog
Innovation extends far beyond product design. From the beginning, we firmly believed that the workplace should be a special place. We believe that people are more creative, focused, and productive in a work environment where they feel trusted, respected, and rewarded. This philosophy later became known as the "Moog philosophy." This principle continues to guide our company today. "In an atmosphere of mutual trust and confidence, work becomes a more rewarding and fulfilling experience for everyone."
Moog's main industry markets in China include plastics machinery manufacturing, power generation, heavy industry, aerospace, and automotive testing. Moog China is our center for automotive testing solutions development and electromechanical pitch control system manufacturing in Asia.
Moog servo valves are primarily used as actuators in electro-hydraulic servo systems (see Hydraulic Servo Systems). In servo systems, hydraulic actuators, compared to electro- and pneumatic actuators, offer advantages such as faster response, higher power output per unit weight, smoother transmission, and stronger anti-interference capabilities. On the other hand, electrical components are often used for signal transmission and characteristic correction in servo systems. Therefore, modern high-performance servo systems also employ electro-hydraulic methods, and servo valves are essential components of such systems.
MOOG servo valves primarily refer to electro-hydraulic servo valves. Upon receiving an electrical analog signal, they output modulated flow and pressure. They function as both electro-hydraulic conversion elements and power amplifiers, converting low-power, weak electrical input signals into high-power hydraulic energy (flow and pressure) output.
