Product Introduction
Pressure Relief Valve
In the petrochemical, energy storage & transportation, and fine processing industries, preventing catastrophic accidents of storage tanks caused by accidental overpressure is the top priority of safety design. The Pressure Relief Valve (also known as Pressure Release Valve) is a key device specifically developed to meet this core safety requirement. As an important component of our high-performance breather valve series, it is designed for direct discharge to the atmosphere, providing reliable overpressure protection while effectively preventing air inhalation and reducing medium evaporation. It serves as an indispensable "safety relief guardian" on top of storage tanks.
Core Functions & Superior Performance
This pressure relief valve features an excellent guiding system, delivering performance that far surpasses ordinary standard valves on the market. Under normal operating conditions, it remains tightly sealed. When the internal pressure of the storage tank rises to the set pressure due to fire, abnormal operation, or other emergencies, the valve disc is lifted accurately, and overpressurized gas is quickly released to the atmosphere, protecting the tank structure from overpressure damage. Once the overpressure is eliminated, the disc resets automatically to restore a tight seal. Focused exclusively on overpressure protection without air intake function, it is a dedicated solution for specific overpressure risks.
Key Customer Value
- Precise & Reliable Pressure Protection: Equipped with an advanced dual-guide system, it ensures smooth and stable opening/closing of the disc with minimal wear. Its leakage rate is well below the strict API 2000 standard, and it maintains industry-leading ±3% set pressure accuracy, guaranteeing sensitive and precise protection actions to avoid misoperation or delayed relief.
- Superior Sealing & Durability: Critical internal components are constructed from corrosion and chemical resistant materials, resisting liquid and vapor adhesion to ensure long-term stability and reliable sealing under harsh working conditions. The disc and seat assembly adopt a field-replaceable modular design, significantly simplifying maintenance and reducing full life-cycle costs.
- Fast Response & High Discharge Capacity: The valve reaches full open position at only 10% beyond the set pressure, ensuring rapid response to timely relief and preventing pressure accumulation. The optimized flow channel design provides large discharge capacity to effectively handle emergency overpressure conditions.
- Wide Operating Adaptability & Flexibility: It operates reliably across a broad temperature range to suit diverse environments. Flexible pressure setting options are available to meet the protection requirements of different storage tanks. Flange connections comply with global mainstream standards including ANSI, DIN, and HG/T20592~20635-2009, ensuring seamless integration and easy installation for various tank projects.
- Cost-Effective Safety Assurance: With a compact, robust structure and effortless installation (requiring no external power or complex controls), it offers a reliable, maintenance-free, and highly cost-effective dedicated overpressure protection solution for storage tanks. It is a fundamental component for building tank safety defense lines.
Typical Applications
- Dedicated overpressure protection for fixed-roof storage tanks, especially for emergency relief during fire scenarios.
- Atmospheric or low-pressure storage tanks used to prevent overpressure caused by rapid filling, solar radiation, or internal reactions.
- As part of the tank pressure protection system, used in conjunction with breather valves, vacuum valves, etc., to provide layered protection.
- Process vessels or storage tanks in chemical, pharmaceutical, and related industries requiring independent overpressure relief protection.
