Abstract :
In order to improve the control performance of some electro-hydraulic digital control system and simplify the system a kind of combination digital valve was designed in the paper. Based on pulse code modulation principle, the combination digital valve which is made of many on-off valves has a lot of advantage such as being simple in structure, good in anti-pollution and cheap, so it is suitable for application in electro-hydraulic servo control system control by the computer of some large-scale mining machinery equipment like the long-distance belt conveyer.
