 Bellows Seal Globe Valve

Bellows seal globe valve is suitable for isolation and flow control duty in industrial, chemical, medical, and power applications. The nominal pressure ranges within PN1.6~4.0MPa, and the allowable working temperature is -29~350℃. According to the actual needs, we will choose different materials, flange, and dimension for users. The valve core can be designed into cut-off type and regulation type upon request.

KIST offers users the most demanding valve customization service according to their specific requirements.

Main Features
1. Bellows sealed globe valve is distinguished for reasonable structure, reliable sealing, great performance and aesthetic appearance
2. Welded with cobalt-based hard alloy by surfacing treatment, the sealing layer, features high abrasion resistance and long service life
3. The quenching and surface nitriding treatment endows the valve with good anti-corrosion and anti-abrasion performance
4. The flow control valve is given double sealing treatment for more harsh environment
5. An indicator is set to show the position of stem intuitively
