All-weather breathing valve overview: All-weather breathing valve is mainly used for oil and liquid tank, to exclude positive and negative pressure gas tank, so that the liquid inside the tank easy to access. There are certain obstacles, tank deformation and vibration may occur, the product design is reasonable, simple structure, easy to use; is an essential product of the tank, indispensable. All-weather breathing valve performance and features: 1. The new all-weather breathing valve housing made of cast iron, cast steel and aluminum alloy, good corrosion resistance; 2. The valve tray with PTFE material, low temperature, antifreeze performance; 3. Simple structure , Easy maintenance, safe and convenient; 4. The new all-weather breathing valve performance in full compliance with the Ministry of Petroleum Industry standard SY7511-87. All-weather breathing valve range: The new all-weather breathing valve for storing flash point below 28 ℃ Class A oil and flash point of less than 60 ℃ of B oil products, such as gasoline, stupid, a stupid, kerosene, light diesel oil , Oil, oil and other oil products and the nature of the chemical storage tanks.

If the tank liquid output when the tank must be drawn into the tank from the outside air (called negative pressure). Stop breathing when the valve is automatically closed will not leak the liquid gas tank, so that the liquid inside the tank has been a good guarantee.
