German API Pneumatic valve API Pneumatic model API Pneumatic price

API Pneumatic valves are devices used to vent air in HVAC systems during operation. During the operation of heating and HVAC systems, gases released from water upon heating, 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 when pipes operate with trapped air; cavitation in circulation pumps.
