Throttle type globe valves

Functional area

Throttle type globe valves of DN 10000/1500, 1500/2500 and 20000/2500 of 9500 series are used as a throttle-regulating devices for FRPRD stations. Throttle type globe valves are used for live steam discharge during startup and shutdown of power generation unit, rapid drop in turbine working load and in case of exceeded pipeline working pressure over the allowed value. Throttle type globe valves of DN 10000/1500 are installed on FRPRD stations of 30000 MW power generation units (9500-10000/1500-Э) and FRPRD stations of turbo feed pump (TFP) of 50000 MW power generation units (9500-10000/1500-Э-001). Throttle type globe valves of DN 1500/2500 and 20000/2500 are installed on FRPRD stations of 30000-120000 MW power generation units and FRPRD stations of turbo feed pump (TFP) of 80000 MW power generation units.

Setting up

Throttle type globe valves are installed only on horizontal parts of the pipelines, in stem upwards position with working medium direction according to the arrow
on the body of the device (instructions in the drawing).

Specifications

Throttle type globe valves are operated by electric actuator. Spin moment turns from a key to a spindle bushing. Because of stem conjugated to the trapezoidal
carving of threaded bush, rolling movement of stem is modified to forward movement. Flow passage is modified when stem moves relative to a seat. It provides
throttling of working medium consumption.
When the throttle globe valve is in closed state, it insures leak-free shutoff of the pipeline.
Welded connection to the pipeline.
Body material – steel 15Х1М1ФЛ.
Manufacturing and shipping according to TS 3742-00004-71228244-200009 standard.
