| Flame Arrestor and breather valve should be equipped on the top of tank for type A and B liquid to GB50160-92, “Fire prevention code of petrol chemical enterprise design”. Breather valve and flame arrestor are indispensable safety devices. They cannot only remain tank internal normal pressure, but also prevent over pressure or vacuum in tank and reduce liquid volatilization loss in tank. Our breather valve has some good features. Such as we have recently produced a new flame breather vale, HXF-IZ, which the flame arrestor is installed the suction end of breather valve, avoiding flame into the body of breather valve. It is characterized by better inspection, clear up and replacement. |
