Air Vacuum Relief Valve Irrigation

Allowing large quantities of air in and out when needed as well as releasing small amounts of air continuously during operation.

Air vacuum relief valve irrigation. The valve closes even with low water pressure and reduces water hammer. The air vacuum relief valve avr is designed to reliably discharge air during system start up and allow air into the line during shutdown. Product features available in dual. Waterman air vents protect irrigation and piping systems by releasing entrapped air as pipelines fill and by providing vacuum relief when lines drain.

Air vacuum relief valves deliver optimum performance and increased efficiency of an irrigation system by preventing air lock problems and back suctioning of debris into the lines. They allow air to escape during system startup by preventing air restrictions water hammer caused by large air masses inaccurate flow meter readings and explosive conditions from air being compressed by water. This helps stop water hammer and resulting system damage. One of the key elements in a drip irrigation system is air relief.

Installation of proper air relief is essential to the proper operation and longevity of piping systems and the proper functioning of system pumps. Installing automatic air relief valves on the end of lateral lines and emitterline will prolong the efficiency of your system. Clogged emitters can create substantial voids in coverage which can lead to dead plants and dry turf. Air vacuum relief flush valves.

One of the key elements in a drip irrigation system is air relief. Combination air vacuum relief and air release valve as the name implies this valve also known as a double orifice valve does the job of the other two in a single unit. The avr offers a commercial non corrosive solution for releasing adequate air flow at the high points of a micro irrigation system during start up and shutdown.

The air vacuum relief valve allows air to escape during the system s initial start and until the pipe or drip lines are full of water. The avr will also prevent system collapse through vacuum relief.
