Explosion Proof Flame Arresting Breather Valve



Breathing valve is a kind of air breather which install on the petrochemical fixed storage tank, in order to avoid tank over the pressure or vacuum making the storage tank destruct, prevent the outside flame enter, reduce the tank fluid volatile.


Explosion-proof fire breathing valve is to maintain the tank pressure balance, reduce safety energy-saving products medium volatile, but also the use of principles of vapor heat transfer, protect the respiratory valve parts is not easy to freeze, the breathing valve to ensure the normal work, equipped with fire retardant explosion-proof function.


Pressure vacuum relief valves (also known as breather valves) are used to prevent the build up of excessive pressure or vacuum in liquid bulk storage tanks.These valves are used to relieve overpressure in a vessels, piping or containers.


ZZFX/ZZFW Series of Explosion-Proof Flame-Arresting Breather Valve use stainless steel, high quality aluminum alloy and cast iron to manufacture, with advantages of light weight and good corrosion resistance performance. Sealing surface (which it's between disc and seat) is made of engineering plastics. When valve is closing, it has a good sealing performance to meet ANSI B16.104 VI standard. Fire resistant layer is made of stainless steel, and uses the porous flame retardant measures, so it has a good fire resistance performance. Whole structure is designed by according to self-operated principles, which is best choice of explosion-proof structure.
