DIN Y Type Bellow Sealed Globe Valve is applied to various kinds of working condition pipelines such as petroleum, chemical industry, pharmacy, fertilizer, and poer industry, etc. Main Structural Features: This product has logical structure, reliable seal, excellent performance and nice design. Sealing face is overlayed by STL, which is friction-resistant, corrosion resistant to ensure a long time use life. Stem heat-treatment and surface nitriding-treatment to ensure function of corrosion resistance and friction resistance. It has double seal, thus the capability is more reliable. The stem may show the position of lift, thus it is more clearer. The parts material, flange and butt welding dimension may selected according to current operating condition or users' requirement to meeting the requirement of various engineering.
