Application
The air vent valve is applicable to be the equipment of quickly discharging air in pipe of industrial medium being water. It is for improving the efficiency of water transporting equipment and protecting pipe free of distortion of damage, so it is the pre-requisite equipment for pipe.
Â
Features
1. It can eliminate air in pipe so as to decrease resistance and save energy.
2. When pipe is under back pressure, the product can absorb air to avoid pipe crack.
3. Floating ball is stainless with long service life, safety and reliability.
