Product Description

Jacket insulation breathing valve product description
JAV-I jacket insulation breathing valve is welded metal jacket on the basis of ordinary all-weather breathing valve, used to install crude oil, gasoline, kerosene, light diesel oil, aromatic and other fixed top storage tank on the main safety equipment, jacket insulation breathing valve is evaporation loss and protect the tank from being damaged by overpressure or vacuum. Suitable for cold areas such as the north, the jacket thermal insulation breathing valve is usually used with the flame arrester.
Features and performance of jacket thermal insulation breathing valve
The shell of the new jacket thermal insulation breathing valve is made of carbon steel, aluminum alloy and stainless steel, which has good corrosion resistance; The valve disc is made of tetrafluoroidal material, which has good low temperature resistance and antifreeze performance; Simple structure, easy maintenance, safe and convenient; The performance of the new jacket thermal insulation breathing valve is fully in line with the provisions of the Ministry of Petroleum Industry standard SY7511-87.
