German bar valve bar model bar price

bar valves are devices used to vent air in HVAC systems during operation. During the operation of heating and HVAC systems, gases released from water when heated, 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, many negative consequences will occur, such as: corrosion caused by oxidation; formation of air pockets in radiators; poor and unbalanced hot water circulation, causing some radiators to be partially cold; noise in pipes when running with air; cavitation in circulation pumps. Therefore, waste gas in the system must be
