High-precision sealing acc. up to ANSI Class V
New technology adopted. The valve seat, made from stainless-steel, is welded with hard alloy. The thickness of the surfacing layer is up to 2.5~3mm, which enables the metal seat to resist friction and enhances the service life.
Spring and soft gasket are both adopted in the B3100M model to form a sealing component with the metal seat. This endues the metal seat with resilient load, ensuring the sealing stability.
Fire tests acc. to API 607 and API 6FA
Various material components are available for a variety of service application up to 500ºC
Surface-hardened ball allows use in more severe applications such as steam, coal, mud, pulp, high temperature gas, oil, petrochemicals and chemicals.
