| Abstract: | A new servovalve using a pressure control pilot state was introduced, which uses two spools instead of single spool in power magnifying stage. Its working principle and relative characteristics was analyzed, it is indicated that this servovalve is suitable for the hydraulic control system of engineering machine, and it is easv to make or assemble, so it is a cheap servovalve. |
