Anti water hammer combination air valve for buildings and pumps fig. FOX 3F-HR

The Mod. FOX 3F HR air valve, installed on vertical pipes in high-rise buildings or pumping stations, ensures correct system operation by allowing air pockets to be vented under working pressure, large air flows to be admitted during draining, and air to be discharged in a controlled way while the pipe is being filled, so as to avoid water hammer.
