American MOOG servo valve

Functional uses:

G761 series electro-hydraulic servo valve can be used as three-way and four-way throttle type flow control valve, which has better control performance when used for four-way valve. This series of valves are high-performance two-stage electro-hydraulic servo valves with a rated flow of 4L / min to 63L / min at a rated pressure drop of 7Mpa. The valve pilot stage is a symmetrical double-nozzle flapper valve driven by a dry double air-gap torque motor; the output stage is a four-way spool valve. The spool position is mechanically feedbacked by a cantilever spring lever. This series of valve has simple structure, sturdy structure, reliable operation and long service life. This type of valve is suitable for position, speed, force (or pressure) servo control systems and has a high dynamic response.

面料: working principle:Inputting a current command signal to the coil of the torque motor will generate electromagnetic force to act on both ends of the armature, which will cause the baffle in the spring tube to deflect. The deflection of the baffle will reduce the flow of a certain nozzle, and then change the pressure on the side of the valve core communicating with this nozzle. Pushing the valve core to move the valve core to the side opens the fuel supply port (P) and a control oil port. The passage between them communicates the oil path between the oil return port (T) and another control port. At the same time, the displacement of the valve core also exerts a force on the spring rod. This force forms a force on the armature baffle assembly. Recovery torque. When this restoring torque is balanced with the torque acting on the armature baffle due to the electromagnetic force of the torque motor, the baffle returns to zero, and the spool valve spool maintains this balanced open position until the input given signal occurs Variety.In short, the displacement of the valve core is proportional to the input current signal. Under a constant pressure drop at the valve port, the load flow through the valve is proportional to the displacement of the valve core.
