Institutional flush valve operating system

Abstract

A toilet room flush valve for use in connection with urinals or water closets includes a body having a water inlet and a water outlet. There is a valve seat in the body between the inlet and outlet and a valve member is movable toward and away from the valve seat to control the flow of water through the valve body. An electric actuator is mounted on the valve body for causing movement of the valve member. There is a first opening in the valve body and a movable valve element extends in through the first opening into the interior of the valve body. A manually movable member, accessible from outside the valve body is used to cause movement of the valve element within the interior of the valve body. There is a second opening in the valve body and an electronic sensor positioned within the interior of the valve body for detecting movement of the movable valve element and an electrical lead which is connected to the electronic sensor and extends through the second valve body opening. The electrical lead is connected, through control circuitry, to the electric actuator whereby sensed movement of the movable valve element will affect controlled operation of the actuator and consequent movement of the valve member to operate the flush valve.
