Transformer Pressure Relief Valve

Product Name: Transformer Accessories Pressure Relief Valve Product material: aluminum alloy, cast iron, and steel springs Product parameters: DN25-DN130 in effective diameter of fuel injection, opening pressure 35-135 ± 5KPA, closing pressure ≥ 72KPA Service conditions: ambient temperature - 30 ℃~40 ℃ Product structure: composed of valve cover, upper valve body, lower valve body, retaining ring, spring, vacuum ring, diaphragm gasket Equicomposition Product description: When the pressure generated by an internal fault in the transformer is greater than the opening pressure of the relief valve, release The valve automatically opens to release the pressure in the oil tank, avoiding deformation and cracking of the oil tank; In the oil tank When the pressure drops to the closing pressure of the relief valve, the valve closes again, eliminating external moisture and Impurities enter the box.
