MIWIVAL Vacuum Relief Valve

Setting Pressure: -500mba!

Vacuum relief valves are protection devices which are typically mounted on a nozzle opening on the top of a fixed roof storage tank.
It is primarily used as a device for relieving vacuum in tanks, containers and process engineering equipment. 

The valve offers reliable protection against vacuum, and prevents inbreathing of air close to the set pressure.
