Description The amplifier is the servo drive for driving and controlling servo valves and proportional valves. It can realize high accuracy control of all kinds of valves. Servo power amplifier can be composed with other hydraulic systems and measuring transducers into an electro-hydraulic servo system, such as valve-controlled cylinders, valve-controlled motors, valve-controlled pumps, to control the displacement, velocity, accelerate, force and other physical quantities.

Application SVA series servo valve amplifiers are specially used for driving and controlling electro-hydraulic servo valves. The amplifiers are mainly for high accuracy controlling of electro-hydraulic servo valves like nozzle flapper servo valves, and jet pipe servo valves, etc. In a hydraulic system, it is possible to control physical parameters, like position, speed, acceleration and force by using various hydraulic devices and measuring sensors. For example: Valve-controlled cylinder, valve controlled motor, valve-controlled pumps, etc.
