A bypass control valve including a wall that defines a first passage disposed along a first axis and having a first portion, a second portion, and a transitional portion disposed between the first and second portion. The transitional portion has a first port, a pivot point, and an annular locking member proximate the transitional portion, with the first port having a sealing surface disposed thereon. The bypass control valve also includes a first bypass passage disposed along a second axis oblique to the first axis. The first bypass passage has a second port, which projects into the transitional portion and which has a sealing surface and a receiver portion. The receiver portion is coupled to the locking members. The bypass control valve further includes a closure member having a first planar surface and a second planar surface with at least one elastomeric member disposed on each of the first planar surface and the second planar surface. The closure member is preferably pivotally attached to the pivot point and movable between a first position, with the first planar surface contiguous to the first port to permit fluid communication between the first portion and the first bypass passage and to prevent fluid communication between the first portion and the second portion, and a second position, with the second planar surface contiguous to the second port to permit fluid communication between the first portion and the second portion and to prevent fluid communication between the first portion and the first bypass passage. The bypass control valve also includes an actuator, which is operable to rotate the closure member between the first position and the second position. The actuator has a shaft coupled to the closure member and extending through the wall to the pivot point along a third axis orthogonal to the first and second axis.
