Exhaust valves are used in the independent heating system, central heating system, heating boiler, central air conditioning, floor heating and solar heating system. Because usually have certain air dissolved in water, and air solubility with the rising of temperature decreases, the water in the process of cycle gas gradually separated from the water, and gradually come together to form a big bubble column, even because there is water, so often have gases.
1. Can eliminate the gas in the pipe, reduce drag and save energy.
2. When the pipe is under pressure, the product can automatically inhale air to prevent the pipe from bursting
3. Floating ball is stainless steel, long service life, safe and reliable.
