Abstract

An isolating valve for a pulverised fuel pipeline comprises a pipeline section (12) in which is mounted an arcuate valve flap (14) pivotal between an open position shown in figure 1 and a closed position wherein the flap blocks the pipeline section and mates with a valve seat (20). In the open position sealing means (28) on the back of the flap (14) close a port (24) for purging air, that port being opened as the flap moves to the closed position. <IMAGE>
