Product Introduction: As a member of the Moog D66x series, this valve is a pilot-operated proportional valve integrated with electronics and an analog interface. Its spool is directly installed in the valve housing and controlled by hydraulic pilot operation. It is developed to meet the needs of high-demand industrial applications, with the advantages of high functional flexibility and excellent dynamic performance, and can accurately control the flow of hydraulic oil in hydraulic systems to achieve precise positioning of hydraulic actuators such as cylinders or motors.
Hydraulic Parameters: The rated flow rate ranges from 30 to 1500 l/min (8 to 395 gpm) when the pressure difference per throttle edge is 5 bar (75 psi). The maximum flow rate can reach 3600 l/min (950 gpm) (ISO specification 10). The maximum operating pressure is 350 bar (5000 psi). The installation type complies with ISO 4401 specifications 05, 07, 08, and 10 (NG 10, 16, 25, and 32). The 100% step response time is 10 to 50 ms when the pressure is 210 bar (3000 psi).
Electrical Parameters: The supply voltage is 24 VDC (18 to 32 VDC), and the rated signal options include +/-10 V, +/-10 mA, and 4-20 mA. The electrical connector models are 6 + PE and 11 + PE.
Functional Features: The valve body is optimally designed to achieve a high rated flow rate. It can be provided in two-stage or three-stage designs according to the required dynamic performance. ServoJet or nozzle baffle pilot valves are optional. The improved pilot stage design enables excellent dynamic response. A variety of fail-safe protection schemes are available to achieve an excellent match with different application scenarios.
Application Scenarios: It is widely used in various industrial fields that require precise control of hydraulic systems, such as machine tools, injection molding machines, and metallurgical equipment. It is especially suitable for occasions that have high requirements for flow control accuracy and dynamic response speed.
