Special Types pressure relief valve (PRV) is also known as Shroud ( Rotatable direction cover ) Type
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.
- Direction cover is used to direct the flow of oil into pipe.
- Direction Cover is rotatable and it can be fix in any direction as per suitable.
Product Overview
The Special Types Pressure Relief Valve (PRV), also known as the Shroud Type or Rotatable Direction Cover Type, is specially designed for transformer applications where controlled oil discharge direction is required. The valve opens automatically when internal transformer pressure exceeds the set limit, releasing excess pressure to protect the transformer and prevent equipment damage.
The integrated rotatable direction cover allows the flow of transformer oil to be safely directed into a connected pipe, improving safety and installation flexibility.
What Is a Shroud Type Pressure Relief Valve?
A shroud type pressure relief valve is an advanced transformer safety valve fitted with a direction cover that guides the released oil flow into a specific direction. Unlike standard PRVs, this special type prevents oil splashing and allows controlled discharge through a pipeline.
The direction cover can be rotated and fixed in any required direction, making it ideal for compact installations and customized transformer layouts.
Working Principle of Special Types Pressure Relief Valve
-
The valve remains closed during normal transformer operation
-
When internal pressure exceeds the preset limit, the PRV opens instantly
-
Excess pressure and oil are discharged through the shroud
-
The rotatable direction cover directs oil flow safely into a pipe
-
The valve closes automatically once pressure stabilizes
This ensures safe pressure release and minimizes environmental and equipment risks.
