Bliwe Steam stop valve flanged principle introduced: 
      Steam bellows globe valve for nominal PN1.6 ~ 16MPa, flammable operating temperature -29 ~ 350 ℃, the explosive, poisonous, toxic fluids, heat conducting oil, ammonia and other media. Widely used: petroleum, chemical fiber textile, plastic and paper, power steel, rubber, printing and dyeing, natural gas and other gas systems, safe and reliable performance, widely used ethylene glycol and other industrial fluids. Drive a manual, gear, electric, pneumatic and so on. Globe valve products, reasonable structure, reliable sealing, rugged double bellows seal design (bellows + filler), stem to ensure zero leakage. No fluid loss, increase plant safety equipment. And in accordance with international standards sealed. Shutoff valve sealing surface Co-based alloy, wear, corrosion, anti-friction performance and long service life. Shutoff valve stem quenched and surface nitriding treatment, good corrosion and anti-friction properties; stem down position indicator, and more intuitive.
