STALL TOOLS

The tool is controlled by the operator by hand or remotely. The tool runs until the operator shuts it off. Torque load will bring it to a stop (stall) when tightening a fastener at which time the operator should shut it off. The tool does not shut-off automatically. Torque is adjusted by adjusting pressure at a regulator that is properly sized to supply the flow requirements of the tool.

PAC TOOLS

(Pressure Activated Control) The PAC tool is controlled by the operator by hand or remotely. The tool runs until the operator shuts it off or until the torque achieves a level very near stall where the PAC valve system within the tool recognizes the near stall condition and shuts-off the tool. The tool will remain off until the operator or remote device allows the tool’s main valve to return to the off position. The PAC valve is then reset and a new cycle can begin. Torque is adjusted by adjusting pressure at a regulator that is properly sized to supply the flow requirements of the tool. The PAC system will operate effectively over 75 PSI to 95 PSI regulator adjustment range. The PAC valve may require some adjustment for operating pressures below 75 PSI
