Design Features

The BX model knife gate is a bi-directional wafer type valve specifically designed for the isolation of pulverized coal burner lines on coal fired boilers during maintenance operations. 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 standard (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.
