Prevents gas bubble disease
Install 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. Must be mounted vertically. Seals from 2 to 100 psi. Under suction, the valve functions as a vacuum breaker. 1” FNPT threads, measures 51/4” H x 2” in diameter. Air discharge rates (cfm): 60 @ 12.5 psi, 100 @ 25 psi and 180 @ 50 psi.
