Product Introduction: It belongs to Moog’s G771 series servo valves. This is a two-stage pilot-operated flow control servo valve with an analog interface. It adopts advanced design and manufacturing technology to ensure high performance and reliability in various industrial applications. The valve is mainly used to control the flow of hydraulic oil in the hydraulic system, so as to realize the precise control of the position, speed, and other parameters of the actuators in the system.
Technical Specifications: The valve adopts a two-stage design with a dry torque motor and a low-friction double-nozzle pilot stage. The installation surface complies with relevant industry standards to facilitate installation and replacement. The weight of the valve is about 3 kg. The storage temperature range is -40 to +60℃ (-40 to +140℉), and the ambient temperature range is -40 to +135℃ (-40 to +275℉). It has good vibration and shock resistance, and can withstand 30 g vibration (3-axis, 10 Hz to 2 kHz) and 30 g shock (3-axis). The seal material is fluorocarbon (FKM) (Viton™ B) with a hardness of 90 Shore.
Functional Features: It has high spool control force and high dynamic performance, which can quickly respond to input signals and realize rapid adjustment of flow. The rugged design ensures long service life and reduces maintenance costs and downtime. It has high resolution and low hysteresis, which can ensure the accuracy of flow control and improve the control precision of the system. It is compatible with a variety of different fluids, increasing its application range. The symmetrical structure design provides maximum stability under various working conditions, ensuring stable and consistent flow output. The zero position can be adjusted on-site, which is convenient for debugging and calibration during use. When the electrical signal is lost, it can automatically return to the zero position for fail-safe protection, improving the safety of the system.
Application Scenarios: It is suitable for various industrial hydraulic systems that require precise flow control, such as the control system of injection molding machines in the plastic industry, which can control the injection speed and pressure by adjusting the flow, thereby improving the quality of plastic products. It is also used in the hydraulic control system of machine tools to control the movement speed and position of the machine tool slides, ensuring the processing accuracy of the workpieces. In addition, it can be applied to the hydraulic systems of metallurgical equipment, mining machinery, and other large-scale industrial equipment to provide stable and precise flow control for the normal operation of the equipment.
