A drain hole for connecting a discharge hole and the inside of a collection container to each other is formed in a valve seat member. A float support is provided with a cylinder portion in which a piston is incorporated in a slidable manner. An vent valve for opening and closing a vent hole by means of a float is provided to the float support. A drain valve which operates between a closing position at which the drain valve closes the drain hole and an open position at which the drain valve opens the drain hole is provided to the piston. A bleed channel for connecting a piston chamber and the discharge hole to each other is formed by an orifice pin mounted in a bleed hole provided to the drain valve.

The present disclosure relates to a steam trap system, including: an inlet port to receive steam; a diversion valve, configured to be mounted on the inlet port and is further configured to be branched to a first passage and a second passage; a bypass outlet, configured to be in communication with the first passage; a trap mechanism, configured to be in communication with the second passage; at least one first sensing unit, configured to generate at least one first sensed signal corresponding to the steam flow characteristics; a control unit, configured to be connection with the first sensing unit to generate an actuating signal; and a valve actuator, configured to be in communication with the control unit to selectively activate either the bypass outlet port or the trap mechanism, to allow separation of the condensate from the steam. Advantageously, the system efficiently removes the condensate from the steam.
