Features
Prevents overpressure bursting or deformation of the tank by vacuum shrinkage.
When the volume of gas in the tank becomes large, the gas will be exhaled; when the volume of gas shrinks, the air will be inhaled.
Can be cascaded with flame arrestors to stop fires.

91 Breather Valve
A safety valve with automatic respiration device to keep the pressure inside the tank within a certain range.
Breather valve is a protective device mounted on oil or liquid tank top to prevent tank damaged due to inside air volume and pressure changed along with tank contents increasing or losing even outside environment temperature affection. The purpose of breather valve is mainly to control the in-breathing and out-breathing of storage tank by protecting the tank under over pressurization and vacuum and possible rupture or imploding. It is available to combine with flame arrester for fire isolation.

TANK BLANKETING SYSTEM
1. Avoid corrosion by air (moisture) entering the storage tank or oxidative degradation of stored liquids.
2. To reduce the risk of explosion, dilute the oxygen in the tank with an inert gas.
3. Protect the environment from direct gas emissions into the atmosphere.
4. Prevent the storage tank from bursting due to extreme vacuum conditions.
