Product Introduction: As part of the Moog D661 series, it is a pilot-operated servo valve with integrated electronics and analog interfaces. The spool of the valve slides in the sleeve and is controlled by hydraulic pilot operation. The design ensures high precision, excellent static and dynamic performance, and is suitable for the most demanding application scenarios, providing high dynamic performance to meet the precise control needs of hydraulic systems.
Hydraulic Parameters: The rated flow rate per land at a pressure difference of 35 bar (500 psi) is 20-200 l/min (5.3-52.8 gpm); the maximum flow rate is 250 l/min; the maximum operating pressure of ports P, A, and B is 350 bar (5000 psi); the maximum pressure of port T with internal Y is 210 bar (3000 psi), and with external Y is 350 bar (5000 psi); the step response time for 0-100% step is 6.5-18 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 6+PE.
Functional Features:
