The turbine has a speed after the quick-shut valve is opened

Thread Content

If the turbine still has rotation speed after the quick-shut valve is opened, are there any other reasons besides internal leakage in the valve itself?

Our original unit was already like this; once the quick-shut valve was opened, the unit would reach a speed of 1000 revolutions per minute. This is usually caused by a regulating valve that doesn’t close properly; another factor to check is whether the turntable is loose.

The problem of the speed control valve not closing properly is mainly caused by long-term operation.
