LBV-H400 — Line Blind Valve
LBV-H400 is available in DN25 ~ DN1000 (NPS 1” ~ NPS 40”), Class150 ~ Class600 (PN16 ~ PN100).
Application
Suitable for metallurgical, chemical, petroleum, natural gas and other pipeline systems to ensure tight pipeline closure.
In a typical gas pressure regulating station the sequence is: Station inlet → Filtration → Regulation → Metering → Outlet.
