Air Purge Valve
Prevents gas bubble disease
These valves should be installed at high points in an aquaculture pressurized water system where air accumulates. Water pressure automatically forces air out, and when water reaches the valve, the internal float creates a watertight seal. The valve must be mounted vertically. It seals effectively at pressures from 2 to 100 psi. Under suction, the valve draws in air, functioning as a vacuum breaker.
Valve has 1" FNPT threads and measures 5 1/4" H x 2" in diameter. Air discharge rates (cfm) are: 60 @ 12.5 psi, 100 @ 25 psi and 180 @ 50 psi.
