The throttle globe valves of series 950 serve as controlled throttling devices of FRPRDS, which perform pressure throttling of the passed medium together with throttling devices sequentially installed after the valves.

They are intended for the live steam discharge in case of starting or stopping the power generating unit, in case of steam requirement per a turbine less than the evaporation capacity of the steam generator, excess steam pressure increase in the system and sudden reduction of the turbine load.
