A manifold, for a refrigeration system, includes a body comprising a bore hole extending through the body, and a plurality of ports including a first process port for adding and removing refrigerant, and a first side port for mechanical connection thereto. The manifold also includes a first ball valve disposed in the body, between the first process port and the first side port. The first ball valve includes a ball recess aligned with the bore hole through the body, and a ball port extending generally transverse to the ball recess and in fluid connection therewith. The ball port includes a narrow end and wider end. The first ball valve is moveable between an open position in which the ball port is aligned with the first side port and the first side port is in fluid connection with the bore hole through the body, and a closed position in which the ball port is out of alignment with the first side port. |
