Brief discussion on the characteristics of bellows globe valve

Bellows stop valve, also known as bellows seal stop valve. The design of bellows seal, relying on stainless steel bellows for the core sealing material of the valve body, graphite seal for the auxiliary seal, effectively eliminate the valve stem packing seal aging fast, easy to leak the problem, so the bellows globe valve does not exist packing compression problems, easy to switch, for large diameter globe valve can be used to balance valve chamber or auxiliary transmission mechanism. Not only improve energy efficiency, but also enhance the safety of production equipment, and reduce the cost of repair and maintenance, to provide a clean and safe atmosphere for the working environment.


Bellows globe valve has the following characteristics:


1. The hand wheel does not lift when the valve is switched, so it can be used in a small space.


2. Valve core and valve seat are sealed with conical surface to prevent internal leakage.


3, sealing surface surfacing CO - based hard alloy wear resistance, corrosion resistance, long life.


4, valve switch, stem lifting position display, simple operation.


5, stainless steel bellows and graphite packing double seal, reliable performance. A packing seal on the stem provides a secondary seal to prevent leakage if the bellows unfortunately fail.
