Quick-Release Valves

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.
