The PS type foam fire hydrant has two outlets of ∮65 or (∮80) for discharging air foam mixture when connecting fire hoses. If using a portable air foam cannon for extinguishing fires, two outlets can be connected simultaneously; if only one outlet is used with an air foam gun, the other outlet can be sealed (simply close the ball valve) to prevent leakage and ensure fluid pressure. When in use, the ball valve of the outlet should be opened only after the hoses and spraying equipment are properly connected, and attention should be given to the direction of valve operation.
