An electrically operated valve assembly having a manual override includes a valve body, an actuation cam, a shaft, a gear, and a biasing member. The shaft is connected to the actuation cam and includes a projection. The gear defines an opening which selectively receives the projection of the shaft to engage the shaft to the gear. In a first operating condition of the valve assembly, the actuation cam is in an engaged position relative to the valve and the shaft is biased to be engaged with the gear. In a second operating condition of the valve assembly, the actuation cam is in a disengaged position offset along the axis of the shaft from the valve handle and at least partially rotated about the axis of the shaft such that the shaft is disengaged from the gear. Further, a master control module can control one or more such valve assemblies.
