5. Operation The UTD30 is a thermodynamic steam trap which use a disc to control the release of condensate and to trap steam. The trap cycles open and closed to discharge condensate close to steam temperature and closes tight between discharges. The disc, which is the only moving part, rises and falls in response to dynamic forces produced by the partial re- evaporation (flashing) of hot condensate. - Page 11 6.3 How to repair or replace the disc/seat: Remove the insulating cover (14) if fitted and unscrew the cap (2) using a suitable socket or spanner. Do not use Stillsons or a wrench of a similar type which may cause distortion of the cap.
- Page 12 6.4 How to clean or replace the strainer screen UTD30: Unscrew the strainer cap (6) using a spanner. Withdraw the screen (5) and clean, or if damaged replace with a new one. To reassemble, insert the screen (5) into the cap (6), then screw the cap into place. Note: A fine smear of 'Molybdenum Disulphide' grease should be applied to the first few threads.
