Designed to maintain tank integrity by releasing excess internal pressure during system failures. Featuring automatic re-sealing mechanisms and extreme temperature resistance.
Pressure Relief Device PRD 1
Designed for liquid-immersed transformers to maintain tank integrity by releasing excess internal pressure during system failures. This versatile valve can be installed in any position or inclination on tank walls or covers without affecting opening performance.
A flanged safety valve for power transformers that releases overpressure between 30-70 kPa. It features a protected internal mechanism and a directional oil drainage system, automatically re-sealing once safe pressure levels are restored.
Our pressure relief valves are engineered to protect your transformer from tank rupture. Once safe levels are reached, the automatic spring-loaded mechanismtriggers an immediate re-seal, preventing external air ingress while the MPRV directional system safely drains excess oil away from critical components.
