The high-pressure trip system of a steam turbine is an important component related to safety, so the reliability of the electromagnetic valves used is crucial. They need to be able to maintain stable performance under long-term operation and frequent operation, and be able to work normally under harsh environmental conditions.

Therefore, the steam turbine AST system usually uses threaded cartridge valve SV4-10V-O-0-220AG with fast response and high reliability. It has a compact structure and convenient installation, suitable for quickly controlling the flow and pressure of the hydraulic system in emergency situations. These solenoid valves can respond quickly and quickly cut off the flow of liquid in the hydraulic system to achieve emergency tripping.

In the emergency trip system of the steam turbine, the solenoid valve SV4-10V-O-0-220AG is connected to the control system and triggers its action through electrical signals. When receiving an emergency trip signal, the control system will send the corresponding signal to the solenoid valve to open or close, thereby cutting off the fire-resistant fuel and achieving emergency shutdown operation.

The solenoid valve SV4-10V-O-0-220AG has sufficient pressure resistance to withstand the high-pressure working conditions in the steam turbine system. It can meet the requirements of high-pressure hydraulic systems through compact design and appropriate material selection. In addition, due to the high-pressure liquid in the hydraulic system, the solenoid valve SV4-10V-O-0-220AG also has good sealing performance to prevent leakage and pressure loss.
