Product Introduction: This product is a member of the D633 series of Moog direct drive servo valves. It adopts a direct drive design, which avoids the leakage loss of the pilot stage, and the dynamic response is independent of the supply pressure. At the same time, it also greatly improves the anti-pollution ability of the valve. The product is mainly used to control the position, speed, pressure or force in the hydraulic system.
Technical Specifications: The flow range is 3.8 l/min to 100 l/min when the valve pressure drop is 7.0 MPa. The maximum working pressure is 35.0 MPa. The resolution is less than 0.1%, and the hysteresis is less than 0.2%. The frequency response is 40 Hz to 60 Hz when the input signal is ±100%. The ambient temperature range is -20°C to 60°C.
Functional Features: The linear force motor with super large driving force directly drives the main spool to move, and the spool position is detected by a displacement sensor. The built-in electronic amplifier performs closed-loop control on the position of the main spool, ensuring control precision. The direct drive design improves the dynamic response speed of the valve, enabling it to quickly respond to control signals. It has strong anti-pollution ability and can work normally in harsh hydraulic oil environments.
Application Scenarios: It is applied in the field of metallurgy, such as the control system of rolling mills and continuous casting machines, to ensure the precision of metal processing. It is used in the hydraulic control system of wind power generators to realize the adjustment of the wind turbine pitch and yaw. In the field of aerospace simulation, it can be used in flight simulators to simulate the flight state of aircraft. In addition, it is also widely used in industrial machinery such as plastic machinery and forging machinery.
