ABSTRACT:
The present invention is a ball valve which may be attached to a fluid pipe for connection/disconnection between an entrance and an exit. More particularly, the present invention is a ball valve having a discharge orifice communicating with ambient air in addition to the entrance and the exit for connection/disconnection between the entrance and the discharge orifice and/or between the exit and the discharge orifice. The ball valve of the present invention may be attached to piping systems such as, for example, the secondary side of a steam trap, which blocks steam but automatically discharges condensed water, and is used for checking a discharging state of the primary side steam trap and/or releasing remaining pressure on the secondary side.
