ABSTRACT:
A thermoplastic lined plug valve is prepared using a plug having a nonlocking taper and a stem at the small end of the plug. The plug is seated initially by forcing the plug into the plug cavity, raising the temperature of the plug valve above the service temperature of the valve body lining until the valve body lining conforms to the valve plug. The valve is then cooled to a temperature below the service temperature of the body lining.
