Abstract: A valve press tool (10) includes a C-shaped frame (12) having an adjustable platen (28) and an over-center lever device (48) at opposite ends (20, 22) of the C-frame. Attached to the over-center device is a pressure plate (40) to which is attached three legs (42) having non-skid ends (44). The pressure plate and legs are located directly opposite each other so that valve components (70) to be serviced may be placed into compression for disassembly. The platen is adjustable by means of an attached threaded rod (26) that threads into a threaded receiver (24) on one end of the C-frame. This adjustability allows the press tool to be used on various valves having different dimensions and heights.
