Abstract:
A three-port valve includes a valve body including a first port, a second port, and a third port, the first port having a first valve orifice and the second port having a second valve orifice. The valve may also include a first valve closure member and a second valve closure member, the first and second valve closure members may be configured to selectively seal the first and second valve orifices, respectively. The valve may further include a solenoid including a first coil and a second coil, at least one of the first and second coils configured to actuate at least one of the first and second valve closure members when energized. Additionally, the valve may include an electrical connection configured to selectively and individually energize the first and second coils. The valve may be configured to operate in at least three different states of operation. For example, the three-port valve may have a first state (e.g., a default state) when neither coil is energized, a second state when first coil is energized to move only one of the valve closure members, and a third state when the second coil is energized to move both valve closure members.
