Product Detail

Product Description

Flanged double-port exhaust valve is suitable for pipelines where the working medium is water. It is used as a device to remove gas in the pipeline to improve the efficiency of water conveying equipment and protect the pipeline from operating normally. If the pipeline vibrates or ruptures, the exhaust valve will inhale at any time to ensure the safety of the pipeline. Double port exhaust valves are widely used in various fields such as municipal construction, farmland water conservancy, thermal power generation, petrochemical industry, metallurgy and mining, fire protection and environmental protection, food, shipping, medicine and light textiles.



Product Features

1. It can eliminate the gas in the pipeline, reduce resistance and save energy.

2. When the pipeline is under negative pressure, this product can quickly and automatically inhale air to prevent pipeline rupture.

3. The exhaust capacity is many times that of the ordinary double-hole exhaust valve.

4. The float bracket is made of stainless steel, which has a long service life and is safe and reliable.
