Product Details
This brass transformer pressure relief valve is mainly used for overpressure protection of oil-immersed transformers. Adopting precision brass casting and machining, the valve body has excellent compactness and corrosion resistance. When the internal pressure of the transformer exceeds the set value, the valve opens quickly to release pressure; after pressure recovery, it automatically resets and maintains reliable sealing. It effectively prevents oil tank deformation and ensures stable operation of power equipment.
