    Oem Bulletin # 13T-06: Unloader Valve Changes

    Uploaded by

    BAMBANG
    The document summarizes changes to unloader and oil control solenoid valves and coils used on Carlyle screw compressors. The old supplier discontinued the original valves, so new valves and compatible coils from a new supplier will be used going forward. The new valves can be identified by hex-shaped stem retainer nuts and part number markings, while the old valves had notches or holes for tools. The changes are effective May 2014.

    Table 2 Solenoid Coils


    The new coils listed are both forward and backward compatible. In other words they can be used with
    either new or old valves. However, old coils cannot be used with the new solenoid valves.

    Identification:

    The old and new valves can be identified by the shape of their stem retainer nuts and the markings
    on the valves. The part numbers are shown on the base of each valve. See Figures 1 - 4.

    Note: 06N compressors manufactured prior to Dec 12th 1998 (S/N: <5098Jxxxxx) used an Alco
    8TB0226 oil control solenoid. The marking on this valve will be different. Both the new valve and coil
    will work on these compressors. Follow the instructions with the service kits

    Models: 05T, 06T, 06N, TS, TT, TU, and TV series screw compressors.

    Reason for Change:

    The old supplier discontinued production of these solenoid valves. A new supplier has been
    qualified and will be used for all future production. The new solenoid valves require a coil with a
    higher temperature rating.

    Effective Date: May2014
