Product Introduction: Belonging to the Moog D66x series, this valve is a pilot-operated proportional valve with integrated electronics and an analog interface. Its spool is directly installed in the valve housing and hydraulically pilot-controlled. It adopts the well-known ServoJet as the pilot valve, which has the characteristics of low but constant pilot oil demand. It is designed for high-demand industrial applications, with high functional flexibility and excellent dynamic performance.
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 of ports P, A, and B is 350 bar (5000 psi). The maximum operating pressure of port T with external Y is 350 bar (5000 psi), and the maximum operating pressure of port T with internal Y depends on the pilot valve. The 100% step response time is 10 to 50 ms when the pressure is 210 bar (3000 psi). The installation type complies with ISO 4401 specifications 05, 07, 08, and 10 (NG 10, 16, 25, and 32).
Electrical Parameters: The supply voltage is 24 VDC (18 to 32 VDC), and the rated signal options include +/-10 V and +/-10 mA. The electrical connector models are 6 + PE and 11 + PE.
Functional Features: The valve body is optimally designed to obtain a high rated flow rate. It can be provided in two-stage or three-stage configurations. The ServoJet pilot valve has low and constant pilot oil demand. The improved pilot stage design ensures excellent dynamic response. A variety of fail-safe options are available to meet the needs of different application scenarios.
Application Scenarios: It is widely used in industrial fields that require precise control of hydraulic flow, such as plastic machinery, forging equipment, and automated production lines. It is especially suitable for occasions with high requirements for system dynamic performance and control precision.
