Pulse Valve 8с
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.
