Proportional hydraulics along with electrical and electronics has enabled precise control of actuators at the same time delivering high power and torque. This technology has found wide range of application in mechatronics, aeronautics, defence and many more.

NiYo Engineers’ Proportional Hydraulic Trainer Kit aims at imparting knowledge of lector-hydraulic servo-proportional system, hydraulic actuators, transducers used for the measurement of oil pressure, oil temperature, rotary speed, position, etc., control signals and controller tuning.

The system aims at studying closed loop feedback control in hydraulics for angular position, rotational velocity and linear position using an Electro- Hydraulic Servo valve. A brake type loading arrangement is provided to vary the load on the hydraulic motor and study its effect.
