Its closing member (valve) along the center line of the valve seat to do a straight line movement, mainly used to connect or cut off the pipeline medium; open and close the valve flap stroke is small, open and close the time is shorter, the valve height is smaller; globe valve and gate valve compared to the structure of the globe valve is simpler, easier to manufacture and maintain. Sealing surface is not easy to wear, abrasion, better sealing, longer life; handwheel rotates in the direction of the clock for the closure; stainless steel globe valve is suitable for all types of corrosive media pipeline, alloy steel globe valve is suitable for high-temperature-resistant steam, oil pipeline.
Globe valve is suitable for Class150~2500, PN10~PN420, working temperature -46~600 ° C petroleum, chemical, pharmaceutical, chemical fertilizer, electric power industry and other conditions of the pipeline, cut off or connect the pipeline medium.
Its main structural features are: 1.
1. The valve can be used bolt bonnet structure and pressure sealing bonnet structure.
2. sealing surface surfacing cobalt hard alloy, wear-resistant, corrosion-resistant, anti-scratch performance is good, long service life
3. the valve stem is tempered and surface nitriding treatment, has good corrosion resistance and anti-scratch.
4. the valve is equipped with inverted sealing structure, reliable sealing.
5. parts material and flange size can be selected according to the actual working conditions or user requirements, to meet a variety of engineering needs.
