Features and Application:
Bellows globe valve adopts sealed stucture.In common valves, the packing seal of the stem ages fast and it is easy to leak,but this design totally eliminates these short comings.Apart from increaseing the efficiency of materials and the safety of production equipment,it not only reduces maintenance the costs and frequent maintenance of products but also provides a clean and safe working environment. Double seal design(bellows and packings),if the bellows invalidates,the stem packings will prevent outside leaking. There are no fluid loss,but it reduces the energy loss and improves the equipment safety. Longer service life,less maintenace and lower operating costs. Firm and durable seal design of bellows ensures the zero leakage of stem and provides more reliable performance and no maintenance. Quenched stem and surface nitridation with good performance of corrosion and friction resistance. Excellent performance,graceful outline,and more visibleness with position indicating of stem.
