Locking piece for air vent and oil drain – Din 42558 / DownloadDescription
The air release valve DIN 42558 is a critical accessory designed to safely discharge the air that accumulates in the tank or radiator sections of oil-immersed transformers. Air accumulation inside the transformer can negatively impact the insulation level of the system and may lead to failures. Therefore, air discharge systems play a vital role in both power and distribution transformers.
At Hann Metal, we offer a high-quality solution to meet this need: the DIN 42558 air release valve. Our products are available in two different models, A6 and A12, and are fully compliant with the DIN 42558 standard. The A6 type is suitable for more compact systems, while the A12 type is preferred in larger transformers where higher air discharge capacity is required.
These valves can be manufactured using various material options such as carbon steel, AISI 316L stainless steel, and duplex steel (1.4462). This allows for the most suitable solution to be provided depending on environmental conditions and project requirements.
