A hydraulic tool for crimping electrical connectors having a die head subassembly in which the moveable power ram is constrained to axial movement along its power cylinder axis and prevented from rotating about the cylinder axis or canting as it moves outwardly of the cylinder during a connector crimping operation.

Hydraulic crimping press for electrical connectors

A valve for use in a hydraulic compression tool. The valve has a frame with a central chamber, a first inlet, a second inlet and a discharged outlet. A first gate is located at the first inlet. A plunger assembly having a first plunger member and a second plunger member are movably mounted in the central chamber with a spring biasing the plunger member against the second plunger member. The second plunger member has a conduit between the second inlet and the first plunger member. The valve has a first home position that substantially prevents fluid from flowing therethrough. The valve has a second manual release position wherein fluid can flow into the first inlet and out the discharge outlet. The valve also has a third automatic relief position such that in the event a predetermined maximum fluid pressure is exceeded a gate will open between the first plunger and the second plunger member to allow fluid to flow from the second inlet through the valve and out the discharge outlet.
