Cast iron low lift safety valve is widely used in petroleum, gas, electricity, chemical industry, etc. It is applicable for water, steam, gas, oil or corrosive medium. The valve is made of cast iron and the working temperature is less than200℃. When the pressure in pipes is higher than permitted pressure, safe valve will open to release pressure to ensure the safety of pipes. When the pressure in pipes is lower than allowed pressure, safety valve will close and the pressure inside pipes will be increased.
