Abstract
A solenoid operated flush valve has a main flush valve body including water inlet and outlet means. The main flush valve body includes generally horizontally extending nipple means which is in fluid communication with the water inlet and outlet means. A flow control means is removably mounted within the nipple means and includes valve insert means and solenoid means in cooperative engagement with the valve insert means. The valve insert means includes first and second ends and a side. The valve insert means includes a first passageway extending axially between the first and second ends thereof and a second passageway extending between one of the first and second ends and the side of the valve insert means. The second passageway is in fluid communication with the water outlet means through the side of the valve insert means. Means cooperate with the solenoid means for selectively blocking the second passageway to thereby regulate the flow of water flushing through the flush valve.
