CentroFlow Bellows Seal Globe Valve is a compact structure that is a kind of control valve which uses bellows for sealing the valve stem components. The bellows valve has a bellow inside, and the lower end of the stainless-steel bellows is welded to the stem to prevent the system fluid from eroding the stem. A Bellows Valve is a valve specially suitable for medium where even minute leakages can be extremely critical. With the expotential growth of new industries such as the chemical and nuclear industry, further completely different approach required for the desired sealing & redundancy has led to the increasing development of Bellow seal globe Valve.
Fully quality controlled and tested CENTROFLOW Bellows Seal globe valve has superior sealing performance and is more efficient to guarantee the security of pipelines with hazardous media than the ordinary globe valve does. It provide the highest fugitive in use of critical processing, and can be considered as a high-quality product for creating a leak-free project. Applications:
Hot and cold water systems
Oli Chemical Industry
Non-acidic and non-flammable liquid fluid
Design Standard: BS – 5352 (Reduced Bore)
Testing Method: API – 598 / BS – 5146
Socket Weld End as per ANSI-B16.11
Butt Weld End as per ANSI-B-16.25 with end pups
Screwed End as per ANSI-B-1.20.1 (NPT)
End to End as per manufacturers spec.
Metal bellows seals the moving stem and increases durability of packed stem seal valves.
Two secondary stem seals: a) Backseat in open position; b) Graphite packing.
Easy Machining and resurfacing of the seats,for various purposes.
Short travel distance of the disc(stroke) between the open and closed positions,Bellows seal globe valves are ideal if the valve has to be opened and closed frequently;
