AST solenoid valve SV13-12V-0-0-00

Short Description:

AST solenoid valve SV13-12V-0-0-00 is a 2-way, 2-position, poppet type, high pressure, pilot operated, normally open solenoid valve. This valve is used in applications requiring low leakage, such as load holding applications or as a general purpose diverter or dump valve.

Product Detail

The AST solenoid valve SV13-12V-0-0-00 is mainly responsible for overspeed protection. During normal operation, the AST solenoid valve is energized and closed, thereby sealing the fire-resistant oil drainage channel on the automatic shutdown emergency trip (AST) main pipe, allowing the oil pressure in the piston lower chamber of all steam valve actuators to be established. When the solenoid valve loses power, then it will open, the main pipe leaks oil, causing all steam valves to close and causing the turbine to stop. The AST solenoid valve is arranged in series and parallel, providing multiple protections. At least one solenoid valve must be opened in each channel to cause a shutdown. At the same time, it also improves reliability, and any one of the four AST solenoid valves that is damaged or refuses to operate will not cause a shutdown.
