Product Details

Product Overview
ZFQ-1 all-weather explosion-proof flame retardant breather valve, also known as LFH-IZ/HXF-IZ flame retardant breather valve, has a novel structure integrating the functions of flame arrester and breather valve. It is a necessary new type of safety equipment for petrochemical storage tanks, with the advantages of good fire resistance and breathing performance, light weight, and convenient maintenance.

Product Features
1. The material design and structure of the new explosion-proof flame retardant breathing valve are reasonable, and the flame retardant and breathing are integrated to reduce costs.
2. The valve disc and valve sealing ring are made of stainless steel and polytetrafluoroethylene materials. Good low temperature resistance and anti freezing performance.
3. The flame retardant breathing valve is a ventilation device installed on a fixed roof tank, which reduces oil evaporation and loss. It is an excellent product for energy conservation and emission reduction, and can save resources for enterprises.
4. It has the characteristic of automatically adjusting the internal and external pressure of oil storage tanks.
5. Simple structure, light weight, easy maintenance, and easy installation.
6. The explosion-proof performance is qualified, and it can resist fire every time after 13 consecutive explosion-proof performance tests.
7. Qualified low temperature and antifreeze resistance: After operating at -42 degrees Celsius for 2 hours, there is no deformation in the sealing of the pressure valve disc and vacuum valve disc.
8. Operate continuously at room temperature of 36 ° C for 72 hours and perform 10000 actions. The contact surfaces of the pressure valve disc, vacuum valve disc, and guide rod show no signs of wear or collision, and the guide rod is sensitive in lifting and lowering without jamming.

Applicable scope
The all-weather explosion-proof and flame retardant breathing valve is suitable for storing Class A oil products with a flash point below 28 ℃ and Class B oil products with a flash point below 60 ℃, such as gasoline, benzene, methyl benzene, kerosene, light diesel, engine oil, crude oil, and chemical product storage tanks with the same properties. It can be used together with the new corrugated flame arrester.
