The bellows globe valve is a kind of globe valve. The globe valve is a forced sealing valve. Therefore, when the valve is closed, pressure must be applied to the disc to force the sealing surface to not leak. The opening and closing part of the stop valve is a plug-shaped disc, and the sealing surface is flat or conical, and the disc moves linearly along the center line of the valve seat. The bellows globe valves produced and sold by Zhongzhi Valve are made of carbon steel, stainless steel, etc. The operation methods can be manual, bevel gear, electric, pneumatic, etc.
The bellows-sealed globe valve adopts a bellows-sealed design, which completely eliminates the shortcomings of common valve stem packing seals that are fast and easy to leak. It not only improves energy efficiency, increases production equipment safety, and reduces maintenance costs and frequent maintenance. , It also provides a clean and safe working environment.
Advantages of bellows globe valve:
1. Double sealing design (bellows + packing) If the bellows fails, the stem packing will also be avoided;
2. External leakage, and comply with international sealing standards;
3. There is no fluid loss, reducing energy loss and improving plant equipment safety;
4. Long service life, reduce maintenance times and lower operating costs.
5. The sturdy and durable bellows seal design ensures zero leakage of the valve stem and provides maintenance-free conditions.
