Automatic Air Vent Pressure Relief Valve

One of the key elements in a drip irrigation system is air relief.

Automatic air vent pressure relief valve.

Installing this valve in place of an existing pressure gauge or an existing manual air relief valve is strongly recommended. System efficiency is maintained by venting air via the air valves from the system that can restrict flow and increase pumping costs. Use them with water oil air and inert gas. Clogged emitters can create substantial voids in coverage which can lead to dead plants and dry turf.

As long as the system has pressure the exhaust valve will continue to vent. Threaded air driven diverting valves for use with threaded pipe these valves have npt connections. Protection is provided by exhausting and admitting air through the air valves during system operations including start up shutdown and critical conditions such as power failures or line breaks. Installing automatic air relief valves on the end of lateral lines and emitter line will prolong the efficiency of your system.

1 air vacuum relief valve. All operate on compressed air to automatically divert flow between ports more quickly than motor driven valves. It can be operated reliably either when the system is running with water added or when the system pressure is too high and adequate drainage is required.
