950-150/250-E Throttle stop valve

The shut-off and throttling valves of 950 series serve as controlled throttling devices of BROU, performing throttling of pressure of flowing medium together with throttling devices installed in series after the valves. They are intended for discharge of sharp steam at start-up or shutdown of the power unit, in case of steam demand for the turbine is less than steam capacity of the steam generator, excessive increase of steam pressure in the system and in case of sudden reduction of turbine load. Pipework connection: under welding.

Maximum pressure drop across the valve: critical. Installation position: on horizontal pipeline sections with direction of medium to the stem through side spigots. Climatic design: ?, ???, ??,?

according to GOST 15150-69. Placement category: 2, 3 according to GOST 15150-69. Valve control: by means of multi-turn built-in electric actuator.
