Product Introduction: It is a product of the Moog D664 series servo proportional valves, which are pilot-operated proportional valves with integrated electronics and analog interfaces. The valve is designed for high-flow hydraulic control scenarios, with a two-stage or three-stage configuration. It has excellent dynamic performance and flow control accuracy, and can meet the control needs of large-scale hydraulic systems. The valve is widely used in various industrial fields due to its reliable performance and flexible configuration.
Control Function: Flow control and pressure control.
Mounting Standard: ISO 4401 Size 10 (NG 32).
Hydraulic Parameters: The rated flow rate per land at a pressure difference of 5 bar (75 psi) is 1000-1500 l/min (264.1-396.2 gpm); the maximum flow rate can reach 3600 l/min (951 gpm); the maximum operating pressure of ports P, A, and B is 350 bar (5000 psi); the step response time for 0-100% step is 10-35 ms.
Electrical Parameters: The supply voltage is 24 VDC (18-32 VDC); the rated signal options are ±10 V and ±10 mA; the electrical connector is 11+PE.
Functional Features:
The valve body is optimized for design, with a large flow passage area and low flow resistance.
It can be configured as a two-stage or three-stage valve according to the dynamic performance requirements of the system.
Optional ServoJet pilot valve, which has low pilot oil demand and stable performance.
Equipped with multiple pressure and flow detection points, it is convenient for system monitoring and fault diagnosis.
The sealing performance is excellent, and there is no leakage under high pressure.
Application Scenarios: Suitable for large-scale industrial machinery, such as hydraulic systems of port cranes and bridge machines; in the field of energy, it is used for flow control of hydraulic systems in wind power generation and nuclear power equipment; in the metallurgical industry, it is applied to the hydraulic control system of steel rolling mills and blast furnaces to ensure stable operation of the equipment; it can also be used in the hydraulic system of ships and offshore platforms to withstand the harsh marine environment.
