Structural features:

This series of composite exhaust valves are suitable for installation in the pump outlet or water distribution pipeline. Used to exclude a large amount of air collected in the pipeline, or in the pipeline at the higher end of the collection of a small amount of air discharged into the atmosphere, in order to improve the efficiency of the pipeline and pumping machine, and in the pipe once the negative pressure is generated, the valve quickly inhaled the outside world air, in order to protect the pipeline due to the damage caused by the negative pressure phenomenon.

I recently purchased a valve product, and I must say, I'm highly satisfied with my purchase. The quality of the valve exceeded my expectations. It's well-built, durable, and functions flawlessly. The installation process was smooth, thanks to clear instructions provided with the product. What impressed me the most was its reliability; it hasn't leaked or malfunctioned since I started using it.
