DN500 flanged cast iron automatic balancing Valve is for cruise liners or nuclear-power ship, including 200dollars freight costs

automatic balancing valves (dynamic balance valve) is balancing flow in heating, cooling and domestic hot water systems. Applications in following:
1.) Variable flow system, typical application in FCU heating-cooling systems and any kind of terminal unit;FCU heating (cooling) systems and from time to time in AHU;
2.) Constant flow system, typical application in FCU heating-cooling systems and in AHU;
3.) Variable flow system, typical application in surface (beam) heating-cooling systems, where we use the same equipment for heating and cooling
4.) Variable flow two pipe heating/cooling system, typical application in FCU systems and any kind of terminal units (e.g. chilled beam)
5.) Constant flow solar systems, typical application for collectors-– mainly for domestic hot preparation and preheating of heating water
6.) Chiller application – primary variable flow O) system with headered pumps and controlled minimum required flow through the chiller plant
7.) One pipe radiator heating systems with thermostatic radiator valves and automatic return temperature limiter
8.) Two pipe horizontal heating systems with individual flat connection, including thermostatic radiator valves, automatic pressure difference controller and zone control;
