 The working principle of the electro-hydraulic servo valve J761-003: If there is an electrical signal input, the armature drives the baffle to rotate, and the baffle is close to the nozzle, reducing the oil discharge area and flow rate of the nozzle, and increasing the oil pressure in front of the nozzle; Otherwise, the oil pressure in front of the nozzle decreases, causing the original electrical signal to be converted into a torque signal, resulting in a mechanical displacement signal, which is then converted into an oil pressure signal. The main parameters of the electro-hydraulic servo valve J761-003 are as follows:

Applicable medium: EH fire-resistant oil;
Working temperature: ≤ 135 ;
Usage: Electrohydraulic conversion;
Pressure environment: 315bar;
Material: Quenched stainless steel;
Sealing material: fluororubber;
