A Pressure and Vacuum Relief Valve (PVRV) is a safety device designed to protect storage tanks and process systems from excessive pressure or vacuum conditions. It helps maintain safe operating pressures by venting excess pressure or allowing air intake to prevent tank collapse.

Key Features:

• Dual Functionality: Relieves excess pressure and prevents vacuum formation.
• Set Pressure & Vacuum Settings: Factory-calibrated for precise pressure and vacuum release points.
• Material Options: Available in stainless steel, carbon steel, aluminum, or corrosion-resistant alloys.
• Flanged or Threaded Connections: Various connection types for easy installation.
• Weather Hood & Flame Arrestors (Optional): Additional protection against environmental factors and fire hazards.

Working Principle:

• Pressure Relief: When internal pressure exceeds the set limit, the valve opens to release excess vapors.
• Vacuum Relief: If the internal pressure drops below the set vacuum level, the valve allows air to enter, preventing tank implosion.

Applications:

• Storage Tanks: Prevents damage due to overpressure or vacuum in chemical, petrochemical, and oil storage tanks.
• Pharmaceutical & Food Industries: Ensures product safety by maintaining controlled pressure conditions.
• Gas Processing Units: Protects pipelines and equipment from pressure fluctuations.
