Product Introduction: It is a member of the Moog D68x series, a pilot-operated proportional valve with integrated electronics and an analog interface. The valve spool is directly installed in the valve body and hydraulically pilot-operated, which can achieve high flow control and has a variety of fail-safe options to meet the needs of different application scenarios.
Hydraulic Data: The rated flow per land at a pressure difference of 5 bar (75 psi) is 1000 – 1500 l/min (264.1 to 396.2 gpm), and the maximum flow can reach 3600 l/min (951 gpm). The maximum operating pressure for ports P, A, and B is 350 bar (5,000 psi). The maximum operating pressure for port T with internal Y is 70 bar (1,000 psi), and with external Y is 350 bar (5,000 psi). The step response time for 0 to 100% step input is 35 to 40 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 or 11 + PE.
Functional Features: The valve body is optimally designed to achieve high rated flow. The pilot stage adopts a Mini DDV with superior dynamic performance and high efficiency, which ensures the excellent dynamic response of the valve. It has low required minimum pilot pressure and integrated amplifiers and control electronics, which improve the functional flexibility of the valve. A variety of fail-safe options are available to ensure the safety of the system in abnormal situations.
Application Scenarios: Developed for demanding industrial applications, it is suitable for fields such as large-scale industrial machinery, hydraulic presses, and heavy equipment. For example, it can be used in the hydraulic control system of large hydraulic presses to control the flow of hydraulic oil and ensure the stable operation of the presses; it can also be used in the control system of heavy mining equipment to adapt to harsh working environments and high-load working conditions.
