Hygienice air release valve(sanitary vacuum valve) is installed on pressure vessel or pipeline system.
And the air release valve have two options:
1)When the pressure is higher than the setting pressure(standard 1bar),air release,otherwise is closed.
2)When the pipe system in vacuum(standard -0.9bar)valve automatically open.It will ensure the equipment and related instrument security. At the same time can meet various production process demands.
AISI304 and 316L
When the tank pressure large than setting pressure,valve will open and relief pressure
Lower than 3.2 bar,Vacuum lower than -0.9 bar
-10 degree C to +120 degree C
