 A
trip throttle valve is located at the main steam inlet of the
turbine and functions to quickly shut off supply steam when an
emergency operating condition occurs. It is an integral part of
the rotating equipment protection system.
A trip throttle valve can also be used during
start-up to warm high-temperature turbine components, to bring
the unit up to minimum governor speed, and to confirm control
system operation.
The Gimpel product line includes mechanical
latch-type trip throttle valves and hydraulic-operated trip and
trip throttle valves.
