Pressure Relief Valve PRV T3

Pressure Relief Valve PRV T3

A pressure relief valve (PRV) in a transformer opens to release pressure when it exceeds a set limit. This protects the transformer and prevents damage to equipment.


  • 70 mm Port  opening size 
  • Operating Pressure: 0.35 kg/cm2, 0.42 kg/cm2, 0.49 kg/cm2, 0.56 kg/cm2, 0.70 kg/cm2.

The Pressure Relief Valve  PRV-T3 is designed for transformer applications to protect equipment from excessive internal pressure. When pressure exceeds the preset limit, the valve opens automatically to release pressure, ensuring transformer safety and preventing mechanical damage.

Manufactured with precision and tested for reliability, the PRV-T3  pressure relief valve is suitable for industrial and power transformer installations requiring consistent pressure control.

How the pressure relief valve PRV-T3 Pressure Relief Valve Works

A pressure relief valve (PRV) installed on a transformer operates as a safety mechanism:

  • Remains closed during normal operating conditions

  • Opens automatically when internal pressure exceeds the set limit

  • Releases excess pressure safely to the atmosphere

  • Closes once pressure returns to safe operating levels

This process prevents transformer tank rupture, oil leakage, and damage to internal components.
