What is an Air Release Valve?
An air release valve is typically used in water or irrigation schemes to ensure that any entrained air in the water system is automatically released in order to maximize the system’s performance.
Entrained air pockets in pipes can cause excessive head loss and flow reductions if air is not effectively released.

Does NRV reduce pressure?
The flow through the non-return valve causes a relatively large pressure drop, which has to be taken into account when designing the system.
There are different types of non-return valves, such as spring-loaded, swing-type, and clapper-type valves.
