1. A manifold for use in a managed pressured drilling operation, the manifold comprising:
at least one housing;
a first passageway and a second passageway defined in the at least one housing;
a first valve assembly comprising:
a first valve control mechanism having one body, the one body being in communication with both the first and second passageways, the one body being movable to synchronously open and/or close the first and second passageways, the one body having a first opening and a second opening extending therethrough; and
a first actuator operably coupled to the first valve control mechanism for actuating the first valve control mechanism to transition the first valve assembly between a first position and a second position, wherein
one of:
(i) in the first position, the first passageway is open via the first opening in the one body and the second passageway is blocked by the one body; and in the second position, the first passageway is blocked by the one body and the second passageway is open via the second opening in the one body; and
(ii) in the first position, the first and second passageways are open via the first and second openings, respectively; and in the second position, the first and second passageways are blocked by the one body;
a third passageway and a fourth passageway defined in the at least one housing; and
a second valve assembly comprising:
a second valve control mechanism in communication with the third and fourth passageways, the second valve control mechanism movable to synchronously open and/or close the third and fourth passageways; and
a second actuator operably coupled to the second valve control mechanism for actuating the second valve control mechanism to transition the second valve assembly between a fourth position and a fifth position, wherein
in the third position, the third passageway is open and the fourth passageway is closed; and
in the fourth position, the third passageway is closed and the fourth passageway is open; and
wherein the second actuator is one and the same as the first actuator.
