Safety relief valve 111-250/400-0b

The main components of the UUTs designed for installation on the "hot" lines of the intermediate superheated steam pipeline, as well as the pipework of the Reduced and cooled steam pipelines of ROU, are GPC valves DN 125/250,150/200 series 875, 392, DN 200/250 series 1029, DN 150/150 series 1202,530, DN 150/200 series 1203, DN 250/400 series 694 and 111. GPCs are controlled by their own working medium (steam), supplied to the servo actuator from a pulse valve. The valves are installed on horizontal pipeline sections with the stem pointing upwards. They are located in places convenient for for maintenance and allow to place in close proximity to them impulse valves. GPC are manufactured in accordance with TU 3740-001-86921904-2013..
