The 7200 emergency relief valve provides emergency protection for storage tanks and is used to handle overpressure that cannot be handled by standard ventilation holes in storage tanks. The size design of BasCo relief valve is reasonable, and the displacement meets the API2000 standard, which is sufficient to cope with emergency evacuation caused by fire. In addition, it can provide high displacement vacuum flow during product emergency evacuation. BasCo relief valve is also very convenient for tank inspection and maintenance.Emergency relief valve mechanism video

If the internal pressure of the storage tank is too high, the hinge cover of the 7200 emergency relief valve will start to open when the predetermined set pressure is reached, releasing the excess pressure. After the overvoltage phenomenon dissipates, the hinge cover resets. The hinge mechanism can prevent misalignment and ensure accurate resetting of the hinge cover. When the vacuum inside the storage tank accumulates excessively, the spring-loaded valve core lifts up, breaking the seal between the valve seat and the valve core, allowing air to pass through the valve orifice plate and release the accumulated vacuum. Once released, the vacuum valve closes again and remains sealed.
