CCP230M AST Solenoid valve for Steam Turbine DEH control


When AST solenoid valves are in normal operation, they are energized and closed by excitation, thus closing the anti-fuel drain channel on the automatic shutdown emergency interrupt (AST) main pipe, so that the oil pressure in the lower cavity of the piston of all steam valve actuators can be established . When the solenoid valve is de-energized and opened, the main pipe will drain oil, causing all steam valves to close and the turbine to stop. AST solenoid valves are arranged in series and parallel, so there are multiple protections. At least one solenoid valve in each channel must be open to cause shutdown. At the same time, the reliability is improved. Any one of the four AST solenoid valves is damaged or refused to operate, and it will not cause downtime.
