A meter bypass adapter has a body having: a first port; a second port; a third port; and a fourth port. At least one valve element is held by the body and moveable between: a first position wherein a flowpath is open from the first port to the second port and a flowpath is open from the third port to the fourth port without a direct flowpath from the first port to the fourth port; and a second position wherein a flowpath extends from the first port to the fourth port bypassing the second port and the third port. A single rotary actuator is held by the body to rotate about an axis and, in turn, shift the least one valve element between the first position and the second position.
