Product Introduction: It belongs to the Moog D661 series, which is a pilot-operated servo valve with integrated electronics and an analog interface. The spool of this servo valve slides in a bushing and is hydraulically pilot-operated. This design ensures much higher accuracy and extremely excellent static and dynamic performance, making it capable of meeting the requirements of high-demand applications with its high dynamic performance.
Hydraulic Data: The rated flow per land at a pressure difference of 35 bar (500 psi) ranges from 20 to 200 l/min (5.3 to 52.8 gpm), the maximum flow is 250 l/min, the maximum operating pressure of ports P, A, and B is 350 bar (5,000 psi), the maximum operating pressure of port T with internal Y is 210 bar (3,000 psi), and the maximum operating pressure of port T with external Y is 350 bar (5,000 psi). The step response time for a 0 to 100% step is 6.5 to 18 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 the electrical connector is 6 + PE.
Functional Features: It is a two-stage valve equipped with a robust Servo Jet® pilot valve. The optimized valve body design ensures a high rated flow. The improved Servo Jet® pilot valve design achieves an excellent dynamic response. Additionally, there are different fail-safe options available to better adapt to various application requirements.
Application Scenarios: It is widely used in industrial fields that require high-precision flow control, such as the electrode position control of steelmaking electric arc furnaces (EAF), the mold oscillation control of continuous casters, and the bending roll and shifting roll control of hot rolling mills.
