Quick-release valves are manufactured in accordance with Technical Specification 3742-002-79315310-2007.
Quick-release valves are used as regulators of fast-response pressure-reducing and desuperheating stations designed for discharge of direct steam at start-up and shutdown of power-generating units, as well as in case of sharp decrease in turbine load and pipeline overpressure. Connection to pipeline – by welding. Operation – automated control by means of electric drive (Э). May be used as stop valve.
