Design Features:
Bellows Seal Globe Valve is a new kind of globe valves with dual-seal. So its sealing capacity is very good. The sealing surface is bead welding with hard alloy and the stem surface is in "nitrogen treatment". Hence it is the valve of attritionresistant, good anti-corrosion performance and long service life.
Field of Application：
Size Range: DN50 and DN400
Temperature: （-）29℃ to 425℃
Allowable Operating Pressure: PN16、PN25、PN40
Bellows Seal Globe Valve is widely used in petrochemical plants, metallurgy, water treatment, thermal power plants and other oil and water vapor pipelines to connect or cut off the medium in the pipeline.
