Product Introduction: It is a servo proportional valve in Moog’s D661 series. It integrates advanced servo control technology and proportional control technology, with high control precision and good dynamic performance. It is an important part of the modern electro-hydraulic control system and can meet the control requirements of various complex industrial equipment.
Technical Specifications: The rated flow can reach hundreds of liters per minute, which can meet the needs of large-flow hydraulic systems. The maximum working pressure is 350 bar, which has strong pressure-bearing capacity. The response time is short, generally within 10-30 ms, which can quickly respond to the control signal. The linearity error is less than 1%, ensuring the linear relationship between the input signal and the output flow or pressure.
Functional Characteristics: It has excellent dynamic response, can quickly adjust the output flow or pressure according to the change of the input signal, and realize the rapid response of the hydraulic system. The valve has a self-diagnosis function, which can monitor its own working status in real time, find faults in time, and send fault signals. It has a good heat dissipation performance, which can reduce the temperature rise caused by long-term operation and ensure the stable operation of the valve.
Application Scenarios: It is widely used in large-scale industrial equipment, such as the hydraulic system of forging presses, to control the forging speed and pressure of the forging press. It is also used in the field of aerospace, such as the hydraulic control system of aircraft landing gear, to ensure the safe landing of the aircraft. In addition, it can be applied to the hydraulic system of marine equipment, such as ships.
