Bellow Sealed Globe Valve Product Structural Features:
DIN Standard Bellow Sealed globe valve ( Os & Y Type ) is applied to various kinds of working conditions of pipelines such as petroleum, chemical industry, pharmacy, fertilizer, and power industry, etc, under nominal pressure in the PN1.6-40 MPa and operating temperature at -20 – 350℃, that is used to cut off or connected to the pipeline medium.
Bellow Sealed Globe Valve 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 sure 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’s requirement to meeting the requirements of various engineering.
