Linear Actuator Override Tool (LAOT)

  • Product Number: ITE-0057-DR-0001-00

    • The linear actuator override tool (LAOT) is used to transmit axial force to the stem of hydraulically actuated gate valves. The tool consists of a bayonet or horse shoe profile end effector that locks the tool to the valve interface and reacts the axial override force generated by the tools piston.
