A manifold and valve assembly includes a manifold block (136) having an inle t (142), an outlet (144), and a conduit in fluid communication with the inlet (142) and with the outlet (144). The assembly also includes a valve (92, 96, 94) having a portion movable within the conduit between a first position blocking fluid communication between the inlet (142) and the outlet (144) an d a second position in which the inlet (142) is in fluid communication with th e outlet (142), a solenoid (184) operable to move the valve (92, 96, 94) from the first position to the second position in response to an electrical input applied to the solenoid (184), and a lever (208, 210, 212) operable to move the valve (92, 96, 94) from the first position to the second position in response to a manual input applied to the lever (208, 210, 212).
