BX – Coal burner isolation knife gate valve
BX model
Bi-directional wafer style knife gate valve for coal burner isolation
The BX model knife gate is a bi-directional wafer valve specifically designed for the isolation of pulverized coal burner lines on coal fired boilers during maintenance. The valve is dust tight which makes it suitable for other bulk handling applications, such as silo outlet valves. This valve has been designed for use in potentially explosive areas (ATEX) and it complies with DIN EN 14460 (Explosion resistant equipment). In the closed position, the valve can be used as an effective measure against flame propagation in the event of an explosion.
