QUALITROL XPRD EXTRA PROTECTION RELIEF DEVICE

50% more tank protection during overpressure events

Mechanical overpressure protection device with integrated directional discharge outlet. Provides pressure relief and insulating fluid containment (requires optional piping) on transformers and load tap changers during overpressure conditions. Automatically reseals once pressure has fallen.

Features

Highest flow rate for quick relief of overpressure
Standard integrated directional shield with 8 inch diameter outlet to maximize flow rate and control hot oil and gas discharge
Corrosion resistant stainless steel directional shield, hardware, and operating valve

50% more tank protection during overpressure events

Larger diameter throat and discharge outlet for increased flow
Flow rate of 12600 SCFM -independently verified by third party or exceeds IEC and CE standards
Dual spring-loaded valve for precise operation and reseal
Patented single-piece, dual-acting gasket for quick, consistent operation with leak-free resealing

Reduce environmental impact and clean up

Improved environmental protection with directed flow for easy clean up
Optional piping can be used to discharge to containment vessels

Protect workers and assets from dangerous oil exhaust

Directed flow with piped discharge dramatically minimized risk of hot oil reaching workers and equipment
Improved environmental protection with directed flow for easy clean up
Optional piping can be used to discharge to containment

Corrosion resistant construction
