Main Control Valve
Large-flow dual-channel main control valve with automatic neutral return and manual override for precise hydro-generator control.
Product Overview
This solution adopts an independently designed and manufactured large-flow 200 mm compound main pressure distribution valve with an independent dual-channel control structure.
In automatic mode, the governor adjusts the oil distribution of the main pressure distribution valve through a proportional valve or servo/stepper motor, enabling precise servomotor movement. In case of power loss or manual switching, the main valve automatically returns to the neutral position to maintain the current operating condition. The mechanical manual operating system can then be used to control the main valve and main servomotor.
