Abstract
The present invention is a tool for inserting an evaporator orifice tube check valve into an evaporator orifice tube. The tool uses a press pin comprising a pneumatically activated cylinder which forces the evaporator orifice tube check valve into the evaporator orifice tube a predetermined distance. The tool also includes a reciprocating cylinder which locates the valve to a proper seating depth, a signal generator which notifies the operator if the valve in a particular evaporator is not seated properly, and a marking device which creates a label on the evaporator orifice tube only if the evaporator orifice tube check valve is at the predetermined desired location.
