Description

Description:

Servo valve G771K202A is a system composed of torque motor, two-stage hydraulic amplifier and mechanical feedback. The first stage of hydraulic amplification is a double nozzle baffle system; the second stage of amplification is a slide valve system.

Torque Motor: An electro-mechanical converter that produces rotational motion proportional to an electrical command signal, used in the input stage of a servo valve. Torque motors include coils, pole pieces, and armatures. The armature is mounted on a thin-walled spring tube that acts as a fluid seal between the torque motor and the hydraulic portion of the valve. The armature, bezel and feedback lever are rigidly held and supported by a thin-walled spring tube.
