What is bellows globe valve ?

Bellows globe valve has a special design for chlorine, liquid chlorine and all kinds of high risk media. In addition to the packing, it also increases the bellows seal, which has a double sealing structure and can effectively prevent the leakage of dangerous media. In the structure, combined with the actual situation of valve application at home and abroad, the valve disc and valve seat sealing pair adopts strong corrosion resistance of polytetrafluoron and Stali hard alloy, stable sealing performance, safe and reliable use, strong corrosion resistance, no medium inside, outside leakage and light operation characteristics. Bellows globe valve is an elastic metal bellows with high performance and long telescopic fatigue life by introducing foreign advanced technology and adopting foreign metal bellows sealing technology.
Bellows globe valve features:
1, reasonable product structure, reliable sealing performance, beautiful appearance;
2, the sealing surface of Co based carbide surfacing, wear resistance, corrosion resistance, friction resistance, long service life;
3, the valve stem conditioning and surface ammonification treatment, has good corrosion resistance and friction resistance;
4, right-angle German standard bellows globe valve double seal, more reliable performance;
5, the valve stem lifting position indication, more intuitive.
Stainless steel bellows globe valve with reasonable structure and beautiful shape. Valve seat adopts elastic sealing structure, reliable sealing, easy to open and close.
The valve stem adopts downward sealing structure, the valve chamber abnormal pressure boost, the valve stem will not be rushed out. Drive mode: manual, electric, pneumatic American standard bellows globe valve can be set 90° switch positioning mechanism, according to the need to lock to prevent misoperation. The sealing pair of globe valve is composed of disc sealing surface and seat sealing surface, and the valve stem drives the disc along the center line of the seat for vertical movement. In the process of opening and closing, the opening height of the globe valve is small, and it is easy to adjust the flow, and it is convenient to manufacture and maintain, and the pressure is widely applicable. Stem axis of globe valve is perpendicular to sealing surface of valve seat. Stem opening and closing stroke is relatively short and has very reliable cutting action, making this valve suitable for medium cutting or regulating and throttling use.
