Inline Air Release Valve 15mm Male BSP Fitting

Sale price$23.50


The two main reasons for an air release valve are: 1. A means of releasing air from the drip line when the system is turned on. Eliminating any air pockets. 2. To allow air to freely enter the system when it is shut down. This ensures a vacuum does not draw debris into the drip line via the dripper outlets. This condition is known as “suck back”. Suck back can cause the drip line to collapse or potentially draw in dirt and block the dripper.
Install one air release valve for every 40Lpm of water flow used in your system. NOT SUITABLE for low pressure applications. The valve needs a minimum operating pressure of 7 meters (70kPa to operate).
