The Role of Air Exhaust Valves in Water Systems

Air exhaust valves are critical components in water distribution systems. They are designed to release accumulated air from pipelines, which, if left unchecked, can lead to air locking, water hammer, and decreased flow efficiency. As a leading air exhaust valve manufacturer, we offer OEM & ODM services, wholesale options, and customized solutions to meet your specific needs.

Impact of Operating Pressures on Air Exhaust Valves

High Pressure Scenarios:
In high-pressure systems, the performance of air exhaust valves is paramount. Elevated pressures can increase the risk of air pockets forming, which can cause significant operational issues. High-pressure conditions necessitate study, durable valves capable of withstanding intense forces without compromising performance.

Low Pressure Scenarios:
Conversely, in low-pressure systems, the challenge lies in ensuring that the air exhaust valves for waterworks operate effectively to release trapped air. Valves designed for low-pressure applications must be sensitive enough to detect and release air at lower thresholds, ensuring smooth operation of the water system.

Influence of Flow Rates on Air Exhaust Valves

High Flow Rates:
In systems with high flow rates, the rapid movement of water can carry air pockets throughout the system. Air exhaust valves must respond quickly and efficiently to release this air, preventing issues like water hammer and flow obstruction. Our air exhaust valves for waterworks are engineered to handle high flow rates, ensuring reliability and efficiency.

Low Flow Rates:
In low flow rate scenarios, air tends to accumulate in certain sections of the pipeline, particularly at high points. Valves must be strategically placed and precisely calibrated to release this air effectively. The design of our waterworks air exhaust valves includes sensitive floats and orifices to cater to varying flow conditions.

Choosing the Right Material for Air Exhaust Valves

Materials play a crucial role in the performance and longevity of air exhaust valves. At Fluid Tech Group, we manufacture valves from corrosion-resistant materials such as bronze, ductile iron, and stainless steel, ensuring compatibility with potable water and durability in various environmental conditions.

Installation Considerations for Optimal Performance

Proper installation is key to the effective functioning of air exhaust valves. They should be installed at high points along the pipeline where air pockets are most likely to form. Vertical installation with the orifice facing upwards is recommended to ensure efficient air release. Depending on the pipeline layout and elevation changes, multiple valves may be necessary.

Specifications of Our Air Exhaust Valves

Our waterworks air exhaust valves range in size from 2″ to 8″ (DN50 to DN200) and are constructed from durable ductile iron per GB12224-2015, EN1074-2000, and EN12266 dimensional standards. With ASME B16.1 Class 125/250 flange connections rated for pressures of 300PSI, 250PSI, or 200PSI, and a maximum temperature rating of 80°C or less, our valves are designed for high performance and longevity. The valve bodies are treated with an ANSI/AWWA C550 coating for corrosion resistance, ensuring durability in demanding environments.
