Abstract
A frost-resistant hydrant includes a conduit or body tube connected with a fluid source, a valve, an actuator stem connected with the valve, and a flow-through stem defined by a fluid passage through the valve and the actuator stem. The valve preferably includes a ceramic disk stack rotatable between an open position and a closed position. A combination back-flow preventer and vacuum breaker is positioned in the flow-through stem. The actuator stem has a rotation limit enabling the valve to move between fully open and closed positions within 90 degrees. A cartridge body incorporating the valve includes an anti-rotation key engaging the conduit and fixing the rotational position of the valve cartridge relative to the conduit.
