The main features of the product structure of the welded bellows stop valve are:

1, the product structure is reasonable, the seal is reliable, the performance is fine, the modelling is beautiful;

2, sealing surface surfacing co-base cemented carbide, wear resistance, corrosion resistance, good friction resistance, long service life;

3, rod and surface nitriding treatment, has good resistance to decay and friction resistance;

4, double seal, more reliable performance;

5, valve stem lifting position indication, more intuitive;

6, parts material, flange and butt welding number size can be based on actual operating conditions or user requirements reasonable matching, to meet a variety of engineering needs.
