Cast Steel Stainless Steel Bellow Sealed Globe Valve For Thermic Oil Use
Product introduction:
The compact structure of a bellow sealed globe valve is utilized to balance the pressure. The Valve is constructed with bellows rather than sttuffing boxes, as is the case with all other valves. Because the valve is entirely closed, the seal prevents leaking. The bellow seal Globe Valve is designed for use in pipelines carrying steam, flammable, explosive, or hazardous media. This sort of valve does not require a flow rate that is fully open or fully closed. Even if the bellows are broken, this valve may resist leaking due to valve system packing because of its structure.
The main benefit of the bellow sealed globe valve is that it prevents fluid loss, which improves the security of the equipment in which it is employed. This valve has a long operational life and requires little maintenance. We are primarily concerned with achieving complete customer loyalty through the provision of high-quality industrial valves.

Product features:
1. The key component of the bellows globe valve is the metal bellows. The lower end is automatically welded to the valve stem assembly, and the upper end is automatically welded to the connecting plate to form a metal barrier between the fluid medium and the atmosphere, ensuring zero leakage of the valve stem.
2. The valve disc adopts a conical design, with a streamlined sealing surface and medium, resulting in better sealing performance and longer service life.
3. Dual sealing design (bellows+packing): If the bellows fails, the valve stem packing will also avoid leakage and comply with international sealing standards.
4. The valve cover comes with a grease fitting, which can directly lubricate the valve stem, nut, and shaft sleeve. Traditional globe valves can only lubricate the threads.
5. Ergonomic handwheel design, longer service life, easy and convenient operation, safer and more reliable.
Product applications:
Chemical, petroleum, electricity, fertilizers, pharmaceuticals, papermaking, and dye industries.
Especially suitable for pipelines with flammable, explosive, toxic, and valuable mediums.
