Air vent valve, also known as air relief valve, is a kind of exhaust device often used in irrigation systems. It can release air in the pipe to ensure pressure balance.
Its working principle is not complicated and is mainly divided into two parts. When the irrigation system starts to run, the pipe will be filled with water, the system pressure will increase, and air will accumulate. At this time, the air can be released through the air vent valve to relieve the pressure and protect the pipe from damage. When the irrigation system is turned off, to prevent the vacuum state in the pipe from causing the pipe to deflate or collapse, air will enter the pipe from the air vent valve. It is precisely because of this mechanism of the air vent valve that the internal pressure balance of the pipe system is protected, thereby maintaining the normal operation of the entire irrigation system.
Air vent valve is not necessarily used in all pipe systems. Usually, it is more used in places with high terrain or where the pressure and water flow in the pipe change greatly. It has various styles and specifications to choose from and is also easy to install. In addition, good air vent valves have high material requirements. They are mainly divided into metal and plastic materials. The air vent valves produced by our company are made of 100% new engineering-grade plastics, which have excellent performance in corrosion resistance, UV resistance, pressure resistance, durability, etc., and can work well even in harsh environments.

We attach great importance to the packaging of our products, because our products need to be exported all over the world and usually need to be shipped by sea for a long distance to reach their destination. To protect the products from damage during long-distance transportation, we will use high-quality, pressure-resistant, and wear-resistant packaging materials. If the customer has specific requirements for packaging, we can also customize it according to customer requirements.
We have a quality inspection process for the production of air vent valves. Professional quality inspectors are responsible for testing the product’s appearance, dimensional parameters, working pressure, intensity, etc. to ensure that the product will not have any quality problems.
Air vent valves have a wide range of applications. As a manufacturer of agricultural irrigation products, the air vent valves we produce are of course mainly used in the irrigation field, such as drip irrigation systems, sprinkler irrigation systems, water pump systems, etc. But the use of air vent valves is far more than that. They can be used in urban water supply and drainage projects, sewage treatment, and industrial fields.
