FLUSH VALVE WITH 3/4" FEMALE

For 0.18 bar water pressure

This one-way valve is used for automatic flushing of water at the beginning 

and the end of each irrigation cycle. At the system start-up, the flush valve
is open, allowing water to flush through the tubing as air is expelled. 
The valve then automatically closes once the system shuts off, and it opens back up, allowing 
Water to drain from the tubing. If your irrigation system needs to be
flushed more frequently, this automatic flush valve makes this task effortless.
To complete your project, please buy 3/4" Male adapter separately
begins to rise to its standard operating pressure.
