A hydraulic tool can include a hydraulic cylinder, a piston within the hydraulic cylinder, and a rotary valve. The piston can be configured to move between a retracted position and an extended position. The piston can include a piston ram and a piston rod that define a ram side and a rod side inside the hydraulic cylinder. The rotary valve can be moved between a first position and a second position. The first position can be configured to direct flow at a first variable speed and a first variable force to the ram side of the hydraulic cylinder and the second position can be configured to direct flow at a second variable speed and a second variable force to the rod side of the hydraulic cylinder.

A crimping tool is described comprising a first crimping member, a second crimping member, at least one intermediate crimping member, a first sliding member and a second sliding member. The free ends of the first crimping member and the second crimping member form an opening of the crimping tool. The first crimping member, the at least one intermediate crimping member, and the second crimping member are sequentially hinged together via connecting devices. The first sliding member is slidably disposed on the free end of the first crimping member. The second sliding member is slidably disposed on the free end of the second crimping member. The first sliding member is adjacent to the second sliding member. The inner sides of the first crimping member, the at least one intermediate crimping member, the second crimping member, the first sliding member, and the second sliding member are formed to be pressed with the workpiece to be crimped. The crimping tool has a simple structure and good crimping performance, so that the workpiece is uniformly stressed and burrs on the workpiece can be reduced.
