0.05-0.1 bar
Connection Size
DN25 to DN100
Pressure Rating
0-10 bar
Opening Pressure
0.2-0.5 bar
Temperature Range
-20°C to 150°C
标准
ISO 5211DIN 11864ASME B16.5

常见问题

What is the primary function of a vent connection in feedwater tanks?

To prevent vacuum formation during drainage and allow controlled release of vapors during heating cycles while maintaining system pressure balance.

How often should vent connections be inspected?

Quarterly visual inspections and annual functional testing are recommended, with more frequent checks in high-cycling or corrosive environments.

Can vent connections be used with different media types?

Yes, but material compatibility must be verified - stainless steel for general applications, with specific seal materials for chemical or high-temperature services.
