The bellows globe valve uses a bellows structure inside. The stainless steel bellows are welded at the bottom to the valve to prevent process fluids from seeping into the valve. The other end is placed between the valve body and the valve, forming a static seal. It adopts a double-seal design; even if the bellows fail, the valve packing can still prevent leakage. The bellows are welded to the valve, maintaining stable performance and preventing valve vibration caused by valve oscillation. It is suitable for media such as steam, flammable, explosive, heat-conducting oil, high purity, and toxic substances.

The bellows are welded to the valve, maintaining stable performance and preventing valve vibration caused by valve oscillation. Suitable for steam, flammable, explosive, heat transfer oil, high purity, toxic, and other media.
Bellows Globe Valve What are the product features?
1. The product has a reasonable structure, reliable sealing performance, and an attractive appearance;
2. The sealing surface is coated with Co-based hard alloy, which is wear-resistant, corrosion-resistant, friction-resistant, and has a long service life;
3. The valve stem is quenched and surface nitrided, providing good corrosion resistance and friction reduction performance;
4. Right-angle German standard Bellows Globe Valve Double seal, more stable performance;
5. Valve stem lifting position marked for more intuitive operation;
6. The material of parts, flange, and butt weld size can be reasonably selected according to actual working conditions or user requirements to meet various engineering needs.
As a user of the equipment, throughout the entire lifecycle of the equipment, the utilization of the equipment should be maximized. In other words, the equipment utilization rate should be as high as possible. Equipment maintenance means stopping production and incurring certain maintenance costs. Bellows valves generally experience wear. If Bellows Globe Valve the valve on the equipment is worn, after a certain period of use, the bellows must be replaced. The lifespan of the bellows depends on the corresponding production process. On the other hand, factors such as corrosion of the circulating medium in the process equipment, temperature during pipeline cleaning and disinfection, working pressure and flow of the process equipment affect the diaphragm's lifespan. Additionally, deformation of the diaphragm globe valve during opening and closing is also an important factor determining diaphragm life.
What is a bellows globe valve?
Most damage to bellows globe valves does not occur during production use but is caused by mechanical squeezing. Although there are waves.
Although bellows in globe valves have different elasticity grades, coatings, and PTFE protective devices, all bellows globe valves experience wear that is not visible externally (surface corrosion and particle adhesion caused by internal media). Therefore, to prevent interruptions in sterile process production due to diaphragm valve failure, it is common practice to replace the bellows before the specified service life. This way, the number of forced bellows replacements, resulting service costs, and equipment downtime are much higher than those of PTFE bellows valves. Another advantage of bellows valves is that model 3360 can be used in almost all process production procedures.
