Cast Steel API Bellow Globe Valve

API bellows globe valves adopts the design of bellows seal. It completely eliminates the shortcoming of fast leakage of the ordinary valve stem packing seal aging. It not only improves the energy efficiency, increases the safety of production equipment, reduces the maintenance cost and frequent maintenance, but also provides a clean and safe working environment; it is applicable to the public. It is said that the pressure is PN1.6 to 16MPa, and the working temperature is -29 to 350 degrees in petroleum, chemical, pharmaceutical, fertilizer, electric power and other industries. The valve is widely used in food, medicine, petroleum, chemical industry, natural gas, iron and steel, environmental protection, paper making and other transportation pipelines to cut off or circulate medium.
