Video introduction

Bellow globe valves use a unique bellow seal design, which completely eliminates stem packing seal leakage and meet the most stringent leakage levels. The zero leakage of bellow globe valves improves equipment safety, saves significant energy, reduces maintenance costs, and provides a clean and safe working environment for industrial applications. The bellow globe valve produced by our company is suitable for heat transfer oil, toxic, flammable, permeable, polluted environment, the pipeline of radioactive fluid medium. 

It has the following advantage:
The sealing surface of the valve seat and disc adopts the form of cone sealing, large force of wedge tightening and good sealing effect, with TCC or STL overlaid on seat, corrosion resistance, wear resistance, scratch resistance, and long service life.
Triple sealing, bellows seal, protective packing seal, stem cone seal in wide open position ensure zero leakage, permanent packing does not need to be replaced
Double or multi-layer stainless steel bellows, good elastic deformation, the number of switching times reaches 10,000 times
Unique bellows and disc integrated assembly, bellows and disc, bellows upper pressure plate welded by argon arc welding, firm and reliable, while completely separating the medium of the cavity from the valve stem to protect the packing and valve stem.
The valve stem passes through the middle inner hole of the bellows to make the bellows and the valve stem separated, effectively preventing common faults such as bellows breaking due to excessive switching or perforation of bellows due to welding defects.
The inverted seal is made of threaded connection sealing seat or body overlay welding austenitic stainless steel, the sealing is reliable, and the replacement of packing can be carried out without stopping, which is convenient and fast and does not affect the operation of the system.
