HVAC systems are used for heating, cooling, ventilation and indoor condition control in buildings, technical facilities, hotels, hospitals, industrial areas and marine applications. Their operation is based on hot water, chilled water, glycol, steam, condensate, condenser water and auxiliary service circuits. Valves in HVAC systems are selected according to flow rate, temperature, pressure, differential pressure, fluid type, circuit function and control system requirements. Correct selection...

HVAC heating systems use hot water, steam, condensate, glycol and auxiliary service circuits to transfer heat in buildings, technical facilities, hospitals, hotels, industrial areas and substations. Their operation is based on controlled flow, pressure and temperature in boilers, heat exchangers, fan coils, air handling units, radiators, underfloor heating circuits and distribution networks. Valves in heating installations are selected according to thermal load, supply and return...

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,...

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...

Hot water and steam networks are used in HVAC installations, industrial buildings, hospitals, hotels, production plants and technical facilities where heat must be transferred with controlled flow, pressure and temperature. Valve and flow equipment selection is based on the thermal load, medium type, operating pressure, supply and return temperature and control system requirements. Hot water circuits operate by circulating water through boilers, heat exchangers, headers, fan coils, air...
