A Pressure Relief Valve (PRV) is a safety device designed to protect pipelines and equipment from excessive pressure by automatically releasing excess pressure.
Remains closed during normal operating pressure.
Opens automatically when pressure exceeds the set value.
Releases excess pressure to protect the system.
Closes again when the pressure returns to a safe level.
Common Applications:
Boilers
Compressors
Pressure Vessels
Steam Lines
Hydraulic Systems
Chemical Plants
Advantages:
• Automatic Overpressure Protection
• Improves Equipment Safety
• Fast Response
• Reliable Operation
• Low Maintenance
Working Principle:
Normal Pressure → Valve Closed
Overpressure → Valve Opens → Pressure Released → Valve Closes
