They are convex and suitable for installation on processes with alternating pressures: underpressure - overpressure. Typical applications are: silos with pneumatic filling, filters, sieves with strong vibrations, etc.. The convex design provides greater stability and greater resistance to loads due to alternating pressures. The burst overpressure at standard vent is 0,1 bar at +22°C.
Burst overpressure: | pstat=0,1 bar at +22°C |
