Product Introduction

The turbine electromagnetic reversing valve (typically integrated into the ETS (Emergency Trip System)) serves as a core control component ensuring unit safety. Classified as a normally energized, power-fail-operated valve, its performance directly determines the reliability of unit shutdown during critical conditions. It must meet stringent requirements including rapid actuation, high sealing performance, interference resistance, and extended service life.

 

1. Product Functions

1) Redundant configuration enhances system reliability;

2) Receives emergency signals to trigger emergency shutdown;

3) Reliable operation with rapid response;

4) Excellent sealing performance and strong venting capacity;

5) Interference resistance, shock and vibration resistance, withstanding unit operational vibrations;

 

2. Common Failures

1) Valve core sticking, preventing operation.

2) Seal leakage.

3) Electrical failure, coil burnout.

4) False trip shutdown or failure to trip during shutdown.
