How to Low Delay in 5G Control
With the rapid development of the digital age, communication technology is evolving at an unprecedented speed. As the fifth generation mobile communication technology, one of its biggest highlights is “low latency”. The so-called delay refers to the time required for data transmission from the sender to the receiver. In the…

How to evaluate the reliability of servo valve
The reliability evaluation of servo valve mainly starts from the following aspects: First of all, the reliability analysis in the design stage is the foundation. In the process of servo valve design, reliability engineering methods, such as failure mode and influence analysis (FMEA) and fault tree analysis (FTA), should…

What is a direct drive servo valve
Direct drive servo valve (DDV) is an electro-hydraulic servo valve that uses a high-power, large stroke force motor or linear motor to directly drive the movement of the power stage spool valve core. It eliminates the complex pilot stage hydraulic amplifier (such as nozzle baffle or jet pipe mechanism) in…

What is a nozzle baffle servo valve？
The nozzle baffle servo valve is a two-stage electro-hydraulic servo valve, and its pilot stage uses a nozzle baffle mechanism as a hydraulic amplifier. It is the most classic and widely used structural form among high-performance electro-hydraulic servo valves. The core working principle is to use a torque motor to…
