Its closing part (valve) moves straight along the center line of the valve seat, mainly used to connect or cut the medium in the pipeline; during opening and closing, the valve height of the stop valve is simple than the globe valve, and it is easy to manufacture and maintain. The sealing surface is not easy to wear, abrasion, good sealing, long life; the hand wheel rotates along the clock direction to close; the stainless steel globe valve is suitable for all kinds of corrosive media pipes, and the alloy steel globe valve is suitable for high temperature resistant steam and oil pipes.
Flange connection globe valve is suitable for the nominal pressure PN1.6~16.0MPa, working temperature -29~550°C, petroleum, chemical, pharmaceutical, chemical fertilizer, power industry and other working conditions of the pipeline, cut off or connect the pipeline medium.
Its main structural features are:
1. The product has reasonable structure, reliable sealing, excellent performance and beautiful appearance.
2. Sealing surface surfacing cobalt-based hard alloy, wear resistance, corrosion resistance, abrasion resistance, long service life
3. The stem has good corrosion resistance and abrasion resistance after tempering and surface nitriding treatment.
4. The valve is equipped with inverted sealing structure, and the sealing is reliable.
5. The material and flange size of the parts can be reasonably selected according to the actual working conditions or user requirements to meet the needs of various projects
