The 7300 Zero-Leakage Emergency Relief Valve is designed to handle overpressure conditions that exceed the capacity of standard vents on storage tanks. Its relief capacity meets API 2000 standards, which is fully sufficient to meet the emergency venting requirements resulting from fires.
As a pressure emergency relief valve, the 7300 Zero-Leakage Emergency Relief Valve has no vacuum capability. When the internal pressure of the storage tank rises to the set pressure, the buckling pin loses stability and bends laterally. Driven by the medium, the valve disc detaches from the valve seat to realize opening and pressure relief.
