Convention
body – steel 20ГСЛ (GOST 108.961.03) with building-up welding 04X19H9C2;
cover – steel 20К (GOST 5520);
valve disk – steel 20 (GOST 1050) with building-up welding 04X19H9C2.
Safety and pulse valves are manufactured in accordance with Technical Specification 3742-002-79315310-2007.
Safety valve is operated by pulse valve. These valves represent a pulse-safety device used to prevent from steam overpressure in pipelines of pressure-reducing desuperheating stations, pressure-reducing stations, deaerators and other facilities of the thermal power plant. Connection to pipeline: 7с-6 – by flange, 7с-8 – by welding (or by flange at the customer’s option), pulse valve – by welding.
