  Valves and flow equipment for ballast water systems

  Posted in: Markets

  Ballast water systems are used for filling, emptying, transferring and treating seawater in ship ballast tanks. Their operation is related to vessel stability, load distribution, trim, draught and water management during ballasting and deballasting. Valves in ballast water networks are selected according to flow rate, pressure, pipe diameter, installation point, seawater corrosion, operating frequency and connection to the ship automation system. In ballast water treatment systems,...

  Valves and flow equipment for exhaust gas and auxiliary boilers

  Posted in: Markets

  Exhaust gas boilers and auxiliary boilers on ships are used for steam generation in main and auxiliary systems. Exhaust gas boilers use heat from the main engine exhaust gas, while auxiliary boilers supply steam when the main engine is not operating or when the available exhaust heat is not sufficient. Boiler-related networks include steam, feedwater, condensate, drain, blowdown, fuel, compressed air, treated water and auxiliary fluid lines. Valve selection is based on operating pressure,...

  Valves and flow equipment for air conditioning and chilled water circuits

  Posted in: Markets

  Chilled water air conditioning systems are used in office buildings, hotels, hospitals, shopping centres, industrial areas and technical facilities. Their operation is based on chilled water production by chillers, distribution through pumps and pipework, and cooling delivery through fan coils, air handling units, heat exchangers and central air treatment units. Valves in chilled water and glycol circuits are selected according to flow rate, supply and return temperature, operating pressure,...

  Valves and flow equipment for district heating systems

  Posted in: Markets

  District heating systems transfer thermal energy from a central heat source to buildings, industrial facilities and substations through hot water or steam networks. Their operation depends on controlled flow, pressure and temperature in the supply and return lines, as well as safe isolation of individual network sections. Valves in district heating installations are selected according to operating temperature, design pressure, differential pressure, required flow rate, network length and...
