ABSTRACT:
A disc valve member (5) is disclosed that can be fitted to a thermodynamic steam trap (1) without modification of the trap. The disc valve member has an internal chamber (7) and perforated portions (8,9) through which air can escape from a chamber (6) in which the disc valve member floats when fitted in a trap, it being desirable that such air escape should be possible during start-up conditions in a steam line. At normal operating temperature, a bi-metal disc (10) within the internal chamber (7) of the disc valve member is snapped-over to a position in which the path for air escape from the trap chamber (6) is closed, and the disc valve member operates as an imperforate member.
