DESCRIPTION
The electrohydraulic servo valve 072-559A is an important component of the hydraulic servo system. It is a hydraulic control valve that continuously controls flow and pressure in proportion by changing input signals. The minimum flow size of the nozzle valve is about 0.2 mm, while the minimum flow size of the nozzle baffle servo valve is 0.025~0.10 mm. Therefore, the nozzle has strong anti pollution ability, high reliability, and long service life. The anti pollution ability of servo valves is generally determined by the minimum flow rate in their structure. However, in multistage servo valves, the minimum size in the front stage oil circuit becomes the decisive factor.
Electrohydraulic servo valves 072-559A have high pressure efficiency and volumetric efficiency, which can generate greater control pressure and flow, improving the driving force and anti pollution ability of power valves.
STATIC CHARACTERISTICS OF SERVO VALVE
1. Pressure - flow characteristics
The pressure flow characteristic curve can be used by system designers to consider load matching and the specification of servo valves for shortcomings. General servo valve samples show dimensionless pressure flow characteristic curves
2. No-load flow characteristics
At rated pressure, when the load pressure is zero, the input current continuously varies between the positive and negative rated currents for a complete cycle. The resulting relationship curve between the output flow and the input current is called the no-load flow curve, or simply the flow curve.
