JAV-I jacket insulation breathe Overview
JAV-I jacket insulation breathing valve for the installation of crude oil, gasoline, kerosene, light diesel oil, aromatics and other fixed top-type storage tank on the main safety equipment, jacket insulation breathing valve is up Evaporation loss and protection of tank against overpressure or vacuum from damage (jacket insulated breathing valve). Jacket insulation breathing valve is usually used with the flame arrester. Jacket insulation breathing valve, jacket insulation breathing valve.
JAV-I jacket insulation breathing valve features
1, jacket breathing valve material made of cast steel, stainless steel, good corrosion resistance.
2, the valve plate, valve ring stainless steel, PTFE material. Low temperature, antifreeze performance is good.
3, the valve is installed on the fixed roof tank ventilation device to reduce evaporation loss of oil, control the pressure of the tank.
4, the valve has a large amount of ventilation, leakage, corrosion resistance, antifreeze good.
5, It can automatically adjust the internal and external pressure on the oil tank and other characteristics.
6, simple structure, light weight, easy maintenance, easy installation.
