Issues with DRESSER-RAND turbine TV and GV valves

Thread Content

What is the reason why, in the case of the control issue related to the two valves for steam supply to the small turbine, the valve cannot be closed when attempting to shut down the machine after the trip lever gets stuck? I wonder if any of you experts have used this device?

After the quick-close valve is opened, rotate the handwheel in the opposite direction to the full-open position; give it a try
