Orbit Brass Misting System Drain Valve 1 pk

The Mist Auto Drain Valve is an essential component for any outdoor mist cooling system. It is designed for installation in one of two ways: either thread it into a 10/24 female-threaded nozzle opening or insert it into any professional Slip-Lok fitting. The auto drain valve is used to drain water from the mist line when it is not in use. It operates as a siphon by drawing the water out of the system once it is no longer pressurized. When installed at low points in the mist line, it works with gravity and allows water to automatically drain from the line; this reduces nozzle clogging and prolongs the life of your mist system.
