Coal Burner Isolation Valves (KCI)

DeZURIK Coal Burner Isolation Valves (KCI) close off pulverized coal burner lines during maintenance shutdowns, providing increased safety by reducing the risk of fires and accidents. DeZURIK KCI valves exceed the NFPA standard of 50 psi internal explosion pressure.

A removable hard-faced seat ring can be easily rotated or replaced, reducing time spent on maintenance. To withstand abrasion or corrosion, DeZURIK KCI valves feature valve bodies and gates of carbon steel or 304 stainless steel. Other options include a stainless steel rising or non-rising stem. A bronze yoke sleeve provides easy actuation and additional resistance to corrosion and wear.

Available in sizes from six to 24 inches (150 to 600mm), DeZURIK KCI valves can be equipped with manual or powered actuators, including handwheel, chainwheel, pneumatic cylinder or electric motor. Flange options include ANSI 125/150, NFPA 85F 1988, or Babcock & Wilcox.
