Reliable Emergency Venting for Critical IndustriesThis pressure vacuum relief valve is purpose-built to protect storage tanks in chemical, petrochemical, and oil & gas facilities. Its high flow capacity and robust sealing mechanisms facilitate safe pressure and vacuum relief, ensuring tank integrity during unexpected conditions. With flameproof construction and corrosion resistance, this valve meets stringent safety and durability standards.
Versatile Design and Mounting OptionsThe valve's dome-shaped, flanged body allows straightforward installation on a range of tank roofs. Available in multiple sizes (4 to 10 inch ports) with lifting or bolted cover types, it fits diverse requirements. Its top-mounted vertical orientation ensures optimal emergency venting performance.
Efficient, Maintenance-Free OperationEquipped with a spring-loaded disc in corrosion-resistant aluminum or stainless steel, the valve delivers reliable automatic relief for both pressure and vacuum situations. Thanks to its robust mechanical control system and tamper-proof features, ongoing maintenance is minimal-reducing operational downtime.
FAQ's of Emergency Pressure Vacuum Relief Valve:
Q: How does the emergency pressure vacuum relief valve function during overpressure or vacuum events?
A: The valve operates automatically, utilizing a spring-loaded disc mechanism that responds to set pressure or vacuum levels. When the internal tank pressure exceeds or falls below specified settings (0.21 to 1.7 bar for pressure, 0.06 to 0.21 bar for vacuum), the valve opens to vent vapors, air, or gas, rapidly restoring safe operating conditions within the tank.
Q: What industries can benefit from installing this relief valve?
A: This valve is ideally suited for chemical, petrochemical, and oil & gas industries where safe emergency venting of large storage tanks is essential. Its robust construction and flexible design meet the demanding conditions frequently encountered in these sectors.
Q: When should this pressure vacuum relief valve be installed on a storage tank?
A: It is recommended to install the valve during new tank construction or when upgrading the safety systems of existing storage tanks. Immediate installation is advised when tanks contain volatile or hazardous substances requiring regulated venting for both overpressure and vacuum conditions.
Q: Where is the optimal mounting position for this relief valve on storage tanks?
A: The valve is designed for top-mounting on storage tank roofs, in a vertical orientation. This position enables effective venting and ensures that overpressure or vacuum relief occurs precisely where needed to protect tank integrity.
Q: What is the process for installing the emergency pressure vacuum relief valve?
A: Installation involves mechanically mounting the flanged base of the valve onto a compatible opening on the tank roof. The valve can be secured using either a lifting or bolted cover, and appropriate gaskets (PTFE or Buna-N) are used to ensure a tight seal between the valve and tank.
Q: How does the anti-corrosive epoxy powder coating benefit the valve's operation?
A: The epoxy powder coating provides a durable, corrosion-resistant layer to the valve body, extending service life and maintaining functionality even in harsh, chemically aggressive environments common in chemical and petrochemical facilities.
Q: What are the advantages of the tamper-proof and maintenance-free design?
A: The tamper-proof construction prevents unauthorized adjustment or removal, ensuring reliable performance. Its maintenance-free design minimizes the need for regular service, reducing downtime and operational costs while maintaining high safety levels.
