Product Introduction: It is a servo proportional valve in Moog’s D661 series. It combines the advantages of servo valves and proportional valves, with high control precision and good stability. It can be widely used in various industrial control systems to achieve precise control of flow and pressure.
Technical Specifications: The rated flow range is wide, which can be selected according to different application requirements, generally from tens of liters per minute to hundreds of liters per minute. The maximum working pressure can reach 350 bar, which can adapt to high-pressure hydraulic systems. The response time is 10-42 ms, which can quickly adjust the output according to the input signal.
Functional Characteristics: It adopts a new type of Servo Jet pilot stage, which improves the dynamic characteristics of the entire valve. The large-flow in-valve flow channel design greatly increases the rated flow of the valve. The main spool position is electrically fed back by a displacement sensor, and the built-in electronic amplifier performs closed-loop control on the spool displacement, ensuring high control precision. It has a fail-safe function, which can ensure that the mechanical equipment is in a safe position in the event of an unexpected power failure.
Application Scenarios: It is widely used in industrial production machinery, such as die-casting machines, forging machines, and plastic injection molding machines, to control the speed and position of the equipment. It is also used in the field of food and beverage processing, such as the control system of filling equipment, to ensure the accuracy and stability of filling.
