Moog D633-536B Direct Driven Valve (DDV)
- Product Introduction: It belongs to the Moog D633 series, a direct-driven servo valve with integrated electronics and an analog interface. The valve uses a permanent magnet linear motor to directly drive the valve spool, eliminating the need for pilot oil, and has the characteristics of high functional flexibility and pressure-independent dynamics.
Detailed content
- Technical Specifications:
- Control Function: Flow control.
- Mounting Pattern: ISO 4401 size 03 (NG 6) or 05 (NG 10).
- Hydraulic Data: The rated flow per land at a pressure difference of 35 bar (500 psi) is up to 40 l/min (10.6 gpm), and the maximum flow can reach 75 l/min (19.8 gpm). The maximum operating pressure for ports P, A, and B is 350 bar (5,000 psi). The maximum operating pressure for port T without Y is 50 bar (725 psi), and with Y is 350 bar (3,000 psi). The step response time for 0 to 100% step input is 12 ms.
- Electrical Data: The supply voltage is 24 V DC (18 to 32 V DC), and the rated signal options include ±10 V, ±10 mA, and 4 to 20 mA. The electrical connector is 6 + PE.
- Functional Features: Driven by a linear force motor, no pilot flow is required, which reduces energy consumption and system complexity. The linear force motor has a large force range, which improves the operating limit of the valve without flow restrictions. The direct-driven design ensures that the dynamic performance is independent of pressure, and the valve has stable performance under different pressure conditions. The current consumption is low near the hydraulic zero position, and when the power supply is cut off, the valve spool is in the spring-centered position, and the actuator stops working to ensure system safety.
- Application Scenarios: Suitable for various industrial fields such as plastic machinery, metal forming equipment, and power generation systems. It can be used in the position control system of plastic extruders to ensure the stable operation of the extruder; it can also be used in the speed control system of turbine generators to improve the control accuracy and stability of the generator.
