As one of the leading stainless steel bellows seal globe valves manufacturers and suppliers in China and equipped with a productive factory, Shanghai Hugo Valve Co.,Ltd is always at your service.
Stainless steel bellows seal globe valves
1,Stainless steel bellows seal globe valves have outstanding performance without leakage, provide a novel solution of environment requirement for long transmission pipelines and devices as on/off valves
2, Unique sealing design of double layers and multi-layer corrugated tube structure ensures to avoid from leakage of conventional valves, meeting the most rigorous sealing standard in the world. It is very important to ensure the manufacturing safety, saving energy and keeping environment clean. Our stainless steel bellows seal globe valve’s production is guaranteed 3 years lifetime under the normal condition and no force majeure.
3, Inside of bellows seal globe valves adopted bellows structure, the bottom end of stainless steel bellows was welded on the stem to avoid the process fluid’s erosion for the stem, the other end of stainless steel bellows was located between valve body and valve bonnet to form static seal. Because of this double seal, the stem packing can protect the valve from leakage if there is problem for the bellows.
1, No leakage loss
2, Simple operation
3, long lifetime
4, No need to maintain, the corrugated tube structure not only prevent the leakage,but also need no maintaining, it is very quick and easy to replace the trim component, all the gaskets are not asbestic also.
5, Stable and endurable
6,The internal trim materials are all stainless steel or special alloy material which is generally used in corrosive environment, there is grease inserting connection on the valve cap for lubricating the valve stem and shaft sleeve.
