High-Capacity Protection for Storage Tanks Valvyn Emergency Vent Valves are designed to provide rapid, high-capacity pressure relief for storage tanks during abnormal conditions such as fire exposure, runaway reactions, or equipment failure. They act as a secondary safety device, protecting tanks from catastrophic rupture.
They are primarily used in situations such as external fire exposure, thermal expansion of stored liquids, runaway chemical reactions, blocked vent systems, sudden vapor generation, or equipment malfunction. During such emergencies, normal pressure relief vents may not provide sufficient capacity, making emergency vent valves an essential secondary protection system.
