7200 Emergency Pressure Vacuum Relief Vent

7200 Emergency Pressure Vacuum Relief Vent is designed to provide an emergency pressure relief opening for storage tanks when exposed to over pressures that are not handled by standard tank vents. These vents provide the capacity to meet API standard 2000 for emergency venting due to fire exposure when properly sized and provides high capacity vacuum flow for emergency pump-out of product. BasCo relief vents also provide quick easy access for tank inspection and maintenance.

When excessive pressure builds within the storage tank , the 7200 Emergency Pressure Vacuum Relief Vent hinged cover begins to open at the predetermined set pressure, relieving excess pressure. When the over pressure has dissipated the cover reseats onto the base. The hinge mechanism prevents misalignment and provides an accurate reseat.

When excessive vacuum builds within the storage tank, the spring loaded pallet lifts, breaking the seal between the seat and pallet, allowing air to pass through the valve

orifice relieving the vacuum buildup. The vacuum valve reseals upon relief and remains sealed.
