DN80 Cast Steel Bellows Globe Valve With Flange
Product Benefits
1.Unlike conventional globe valves that rely only on padding seals,
our bellow seal globe valves utilize a dual sealing system,
combining bellows and padding for superior leak protection.
2.The disc features a specialized scraping design, significantly
increasing durability and extending its service life.
3.The internal bellows are made from high-quality stainless steel
321, providing excellent corrosion resistance and long-lasting
reliability.
4.Designed with a lighter structure, our bellow seal globe valves
ensure easier and more efficient operation compared to standard
globe valves.
