Product Introduction
Pressure Emergency Relief Valve
In high-risk industries such as petrochemicals and energy storage and transportation, when standard pressure relief measures are unable to cope with extreme overpressure conditions such as fires and violent reactions, storage tanks face the risk of catastrophic rupture. The Pressure Emergency Relief Valve is the ultimate safety barrier designed for such the most severe emergency situations. As the last line of defense on the top of storage tanks, it is specifically designed to handle emergency overpressure far beyond the capacity of normal breather valves. Its enormous discharge capacity is sufficient to meet the emergency relief needs caused by fires, serving as a "safety rupture disc" to protect large storage tanks from catastrophic overpressure damage.
Core Functions & Superior Performance
This valve is used to release extreme overpressure inside the storage tank that cannot be handled by conventional pressure relief holes. When the internal pressure of the tank rises sharply to the set pressure due to emergencies such as fires, its hinge cover opens quickly for large-scale pressure relief; after the overpressure is eliminated, the unique hinge mechanism ensures the hinge cover resets accurately. The valve focuses on providing extremely high emergency discharge flow and does not have an air intake function, making it a dedicated, high-performance safety device for dealing with the most dangerous overpressure conditions.
Key Customer Value
- Extremely High Discharge Capacity and Reliability: The discharge capacity strictly complies with the API 2000 standard, specially designed to meet emergency relief needs such as fire conditions. Each valve undergoes strict inspection and leakage testing before leaving the factory to ensure foolproof performance at critical moments.
- Precise Setting and Ultra-Low Leakage: Adopting high-performance sealing and structure, its leakage rate is far below the API 2002 standard, and it ensures a high set pressure accuracy of ±3%, maintaining tight sealing in non-emergency states to avoid unnecessary medium loss.
- Robust Full-Open Structure and Durability: It adopts a full-open structure, providing an unobstructed flow channel during relief to ensure maximum discharge efficiency. All components are made of corrosion-resistant materials, suitable for harsh working conditions, and all internal components can be replaced on-site, facilitating maintenance and reducing lifecycle costs.
- Authoritative Certification and Performance Guarantee: Certified discharge curves are provided to offer a reliable basis for safety system design. Flange connections support global mainstream standards such as ANSI, DIN, and HG/T20592~20635-2009, ensuring seamless alignment with international project specifications.
- Ultimate Protection for Critical Occasions: As a supplement to the standard pressure relief system, it provides a definitive protection solution for storage tanks to cope with the most extreme overpressure conditions. It is an indispensable key equipment in the safety design of large atmospheric storage tanks and dome-roof tanks (especially nitrogen-sealed tanks), and can also be used as an inlet and outlet during inspection and maintenance.
Typical Applications
- Emergency fire relief protection for large petroleum and chemical storage tanks.
- Atmospheric dome-roof tanks, especially those equipped with nitrogen sealing systems.
- Working conditions where the discharge capacity of standard breather valves or pressure relief valves is insufficient.
- Used as a backup inlet and outlet for tank inspection and maintenance.
- Process vessels in the chemical and pharmaceutical industries that need to cope with extreme overpressure risks such as violent reactions.
