Difference and comparison between bellows globe valve and common stop valve

- Nov 08, 2018-

Bellows globe valve is also called bellows sealing globe valve. Through automatic rolling welding, a metal barrier is formed between the fluid medium and the atmosphere to ensure the zero leakage design of the valve stem. Compared with traditional globe valves, it has the following advantages:


1, bellows globe valve has a long service life, reduces maintenance times and reduces operating costs. Rugged bellows seal design ensures zero leakage of stem and provides no maintenance conditions.


2. The opening and closing moment of the valve is small, which reduces the labor intensity, and can drive any type of driving device for remote control.


3. Beautiful appearance, smooth flow line of valve passage, reducing the flow resistance coefficient of valve, is a high-quality energy-saving product.


4. The outer seal of the valve adopts bellows seal and graphite and stainless steel gasket seal. The seal is reliable, and no replacement of sealing filler is needed for long-term use. In industrial use, leakage caused by globe valves: high temperature, highly toxic, flammable and explosive, radiative media, etc., not only pollutes the environment, but also often causes significant personal and property losses. And this kind of valve should be more safe and stable, and strictly adopt foreign advanced standards in design and manufacture.
