Product Introduction: It is a member of the Moog D663 series, which is a pilot-operated proportional valve. This series of valves is designed with demanding industrial applications in mind, featuring high functional flexibility and excellent dynamic performance. The valve adopts a pilot-operated structure, which can achieve higher flow rates and has a variety of different fail-safe options.
Mounting Pattern: It complies with the relevant specifications of the D663 series, and the specific size needs to be determined according to the actual model configuration.
Hydraulic Data: The flow range is 30 – 1500 l/min (under a 1.0 MPa valve pressure drop), the maximum operating pressure is 35.0 MPa, the resolution is < 0.2%, the hysteresis is < 1.0%, and the response time is 10 – 42 ms.
Electrical Data: It is equipped with integrated electronics, and the specific electrical parameters are consistent with the standard configuration of the D663 series, including the supply voltage, rated signal, etc.
Functional Features: The valve body is optimally designed to ensure a high rated flow. It has high functional flexibility and can be configured according to different application requirements. The pilot-operated structure ensures excellent dynamic performance, and there are multiple fail-safe options to improve the reliability of the system.
Application Scenarios: It is widely used in the field of metallurgical machinery, such as the control of blast furnace top pressure recovery turbines, the liquid level control of tundishes and ladles of continuous casters, and the AGC control of thick plate rolling mills. It can also be applied in steam turbines, gas turbines, and other equipment.
