Abstract: A three-way valve for a liquid fuel supply system includes a housing defining a liquid fuel inlet, a purge gas inlet, and at least one drain port. The liquid fuel inlet is sized to receive liquid fuel therethrough for selectively channeling the liquid fuel to a combustor of a gas turbine engine. The purge gas inlet is sized to receive purge gas therethrough for selectively purging liquid fuel from said three-way valve. The at least one drain port is oriented to selectively channel liquid fuel from said three-way valve when purge gas is purging liquid fuel from said three-way valve.
