The spray bar valve consists of a pressure cylinder (3) with an extended piston rod (4). The cylinder (3) is screwed into the wall of the spray bar and the piston rod or valve spindle (4) protrudes into the spray bar to the opposite wall in which the valve seat (7) with the spray nozzle (14) is mounted. The end of the valve spindle (4) facing the valve seat is fitted with a valve cone (6) which is mounted so as to be capable of movement in relation to the valve spindle. |
