YSF20-130 Series Pressure Relief Valve

The YSF20-130 series pressure relief valve is specially developed for offshore wind turbine tower transformers or nacelle transformers. Its characteristics are stable performance, compact structure, high environmental and anti-corrosion performance, and the valve body, valve cover, and standard parts are all made of 304 or 316 stainless steel material. It can also be applied to the pressure release inside the oil tank of large oil immersed power transformers, power capacitors, reactors and other equipment when the pressure exceeds the limit.
