A hydraulic control apparatus for a hospital bed includes a manifold having a manifold block with an inlet, an outlet, and a conduit in fluid communication with the inlet and the outlet, and a valve assembly having a valve with a portion moveable within the conduit between a first position blocking fluid communication between the inlet and the outlet and a second position in which the inlet is in fluid communication with the outlet. The control apparatus further includes a solenoid operable to move the valve from the first position to the second position in response to an electrical input applied to the solenoid, and a lever operable to move the valve from the first position to the second position in response to a manual input applied to the lever.
