A valve control mechanism for operating a plurality of valves in a bank of valves which can be selectively operated by interchangeable lever arrangements one of which has a separate lever for each valve and another of which has a single lever for a pair of valves. The bank of valves and the lever arrangements are detachably removable independently of each other to permit easy servicing and selecting of the desired lever arrangement or to change the sequence of valve operation. |
