Apparatus for delivering a liquid or gaseous medium to a plurality of discharge points 3 in a feed line 2, comprises a feed line having said discharge points arranged at intervals along said feed line 2, a first supply line 6 for the medium connected to one end 4 of said feed line, a second supply line 61 for the medium connected to the other end 41 of said feed line, a valve (5, 51) in each of said first and second supply lines which valves are so interconnected 7 that when the flow of medium is at a maximum in the first supply line, the flow of medium in the second supply line is at a minimum and vice-versa, whereby on operation of the valves during continuous flow of the medium a zone of no or minimum flow velocity travels in said feed line from one end thereof to the other. The valves may be coupled mechanically, pneumatically, magnetically or electrically, and more than one feed line and more than two valved supply lines may be employed. The apparatus may be used to spray molten urea in the manufacture of melamine.
