Product Introduction: It belongs to the Moog D633 series, which is a direct-operated servo valve with integrated electronics and an analog interface. The servo valve adopts a direct drive method with a permanent magnet linear motor, which directly drives the spool to move without the need for pilot oil. It is designed to meet the high-demand requirements of customers, with high functional flexibility, pressure-independent dynamic performance, high driving force, and low power consumption.
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), the maximum flow is 75 l/min (19.8 gpm), the maximum operating pressure of ports P, A, and B is 350 bar (5,000 psi), the maximum operating pressure of port T without Y is 50 bar (725 psi), and the maximum operating pressure of port T with Y is 350 bar (3,000 psi). The step response time for a 0 to 100% step is 12 ms.
Electrical Data: The supply voltage is 24 V DC (18 to 32 V DC), the rated signal options include ±10 V, ±10 mA, and 4 to 20 mA, and the electrical connector is 6 + PE.
Functional Features: It is directly driven by a linear force motor, without the need for pilot flow. The linear force motor has a large force range, which improves the operating limit and has no flow limitation. The direct drive design ensures pressure-independent dynamic performance. The current consumption is low at and near the hydraulic zero position. When the power supply is cut off, the spool is in the spring-centered position, and the actuator stops working.
Application Scenarios: It is suitable for electro-hydraulic position, speed, pressure, or force control systems, especially those requiring high dynamic response, such as the control systems of metal forming equipment, die-casting machines, and other industrial machinery.
