Product Introduction: It belongs to Moog’s D633/634 series of direct-acting servo valves. It uses a linear force motor with ultra-large driving force to directly drive the main spool to move. The spool position is detected by a displacement sensor, and a built-in electronic amplifier performs closed-loop control on the main spool position. This design makes the valve have excellent performance and is suitable for various industrial hydraulic systems.
Technical Specifications: The flow range is 3.8-100 l/min (at a valve pressure drop of 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 40-60 Hz (for ±100% input signal). The working pressure is 14.0 MPa.
Functional Characteristics: The direct-acting design avoids the leakage loss of the pilot stage, and the dynamic response is independent of the oil supply pressure, which greatly improves the anti-pollution ability of the valve. It has high performance, low price, and is easy to use. The built-in electronic amplifier simplifies the system configuration and reduces the difficulty of system integration.
Application Scenarios: Suitable for various industrial fields that require high-precision hydraulic control, such as metal forming machinery, injection molding machines, and machine tools. It can also be used in the hydraulic control system of aerospace equipment to ensure the precise movement of the equipment.
