Pneumatic Trip System

Test the trip valve without tripping the turbine

 

Elliott Partial Stroke ActuatorTesting or exercising a trip valve regularly can mean the difference between a turbine tripping when necessary and catastrophic failure. Elliott's patent-pending, pneumatic trip system with partial stroke actuation provides a safe, efficient, and convenient way to test the trip valve without interfering with the turbine's operation or its ability to trip if an overspeed event occurs. In a matter of seconds, turbine operators can determine if the trip valve is functioning properly.

 

Available for new equipment or retrofit, Elliott's partial stroke pneumatic trip system eliminates the oftentimes inconvenient testing process that requires the turbine to be tripped, taking it offline. The partial stroke functionality enables operators to quickly and easily test the trip valve while the turbine is in operation. This efficient testing process ensures that the trip valve is working properly and improves the reliability of the turbine.Turbine operators can initiate the partial stroke locally or remotely via a distributed control system (DCS).The partial stroke pneumatic trip system can be adapted to any equipment configuration.
