The system drives the cylinders of the intake cylindrical valve of hydro sets in synchronised motion. Flow feedback and servo control are used, with fully domestic software and hardware. Installation is simple with little site work and no intermediate transmission; any opening position can be set to millimetre accuracy; the main hydraulic unit is compact and highly integrated, needing no civil works. Its all-digital design uses domestic key components, closing the gap in independent high-precision cylindrical valve control for large hydro units.
