US MOOG Moog Servo Valve
MOOG was founded more than fifty years ago, initially engaged in the design and supply of aircraft components. Today, the company's motion control technology is widely used in civil aircraft cockpits, generator fans, Formula One racing, medical infusion systems, and many other markets and applications, effectively improving the performance of related products. The history of the company originated from the company's founder William C. Moog, who was an inventor, entrepreneur, and visionary.

Flow control servo valve and servo proportional valve
The Moog flow control servo valve with mechanical feedback is a throttling type flow control valve suitable for 3-port and ideal 4-port applications. Their high-performance two-stage design has a rated flow rate of 3.8 to 227 l/min at a valve pressure drop of 35 bar. Main valve level. The output stage of the valve is a closed center four-way spool valve; the pilot stage is a double nozzle flapper valve. The design of the valve is simple and durable, providing reliable and long-term smooth operation.
Flow control valve with fieldbus interface.
Servo valves with built-in fieldbus interfaces (CANopen, EtherCAT or Profibus DP V1) can set operating parameters, open the valve and monitor its operating performance.
The flow control valve with analog interface is equipped with integrated circuit. The servo valve can be integrated into the valve body with the amplifier and related circuits.
Without integrated circuit, the servo valve uses an external amplifier card to convert the input signal into a control current that drives the torque motor of the servo valve.

Servo valve and servo proportional valve accessories
Servo valve and servo proportional valve with special functions to meet the accuracy requirements, to achieve a high degree of safety and flexibility
Moog is the first to develop servo valves and servo proportional valves with good safety functions such as fail-safe and anti-riot options. It also provides special performance modification support services.
Moog has a long history and rich experience in providing good features required for demanding applications. For example, the fail-safe servo valve in our best-selling servo valve is the key equipment in the machinery used in various applications that require maximum protection for operators. Our explosion-proof servo valve product series can be used in environments where there is a risk of explosion or fire. In addition, Moog is proficient in customizing products and improving performance by modifying product components.
Moog has a good tradition of working closely with customers, which means that we have extensive experience in designing and manufacturing special valves. For example, many of our servo valves provide special construction and modification options to obtain explosion-proof certification, which is suitable for environments that may cause fire hazards due to the presence of flammable gas or steam, flammable liquid, combustible dust or flammable fibers. Another special modification service that Moog often performs is to customize the spool zero cut to solve special system or mechanical problems.
