German Nedschroef valves Nedschroef models Nedschroef prices

Nedschroef valves are devices used to vent air in HVAC systems during operation. During the operation of HVAC systems, gases released by heating water, such as hydrogen and oxygen, can cause numerous adverse effects that damage the system and reduce thermal efficiency. If these gases are not vented in time, they can lead to many negative consequences, such as: corrosion caused by oxidation; formation of air pockets in radiators; poor and unbalanced hot water circulation, causing partial lack of heat in some radiators; noise from pipes running with air; and cavitation in circulation pumps.
