The expansion tank needs to be isolated from the hydronic loop before opening the vent on the bottom of the Airtrol expansion tank fitting. That means there should be a gate or ball valve in the pipe, leaving the boiler system and running to the expansion tank. Therefore, an isolation valve...
Height (in.): 29 – 160 *Typical Stock Item request more information CX Series Taco CX Expansion Tank has a Heavy-Duty Butyl Rubber Diaphragm "Limited Acceptance” Design—For small heating installations and most chilled water applications where smaller air volumes and expanded fluid volumes are...
The air in the tank is compressed. According to Boyle's gas law, the gas is compressed to a small volume, and the pressure rises to store energy. The expansion of the compressed gas can press the water in the rubber diaphragm out of the tank. Product Parameters Model Nominal Diameter...

I've never seen safety or relieve valves installed on these tanks. This is low pressure, low temperature HVAC system tank, that is there for operational purposes only. It's not a compressed air receiver. It allows the system water going from cold to warm to have somewhere to expand, so ...
When water is heated, it expands, and the volume increases. In a closed plumbing system, the expanding water has nowhere to go and can cause pressure to build up, potentially leading to leaks or damage to the water heater or plumbing system. An expansion tank provides a space for the expa...
Note that in an open expansion tank fresh air is constantly absorbed in the water and tends to corrode the system. Open expansion tanks must also be located above the highest heating element, in general on the top of buildings, where they may be exposed to freezing.Closed Compression ...
