Product Introduction: This product is highly similar to the Moog D661-4695C and also belongs to the D661 series of pilot-operated servo valves. It integrates electronics and an analog interface, adopting a hydraulic pilot-operated spool structure. This structure enables the valve to have high control accuracy and stable dynamic performance, and it can operate stably in complex industrial environments.
Hydraulic Data: The rated flow per land at a pressure difference of 35 bar (500 psi) is 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 are ±10 V, ±10 mA, and the electrical connector is 6 + PE.
Functional Features: It has the same functional characteristics as the D661-4695C, including a two-stage valve structure with a Servo Jet® pilot valve, an optimized valve body for high flow, excellent dynamic response, and multiple fail-safe options.
Application Scenarios: It is applicable to various industrial automation fields that require precise flow control, such as the position control of the unwinding arm of hot-rolled steel coilers and coil boxes, the stepping control, and the mandrel control.
