Control Valves and Drains
Nonindicating Control Valves
Underground Curb Valves An underground curb valve is located in the underground piping. It operates similarly to a gate valve. A shaft runs from ground level (or street level) down to the top of the valve. A “curb key,” a long shaft with a tee handle and a fitting designed to fit over the valve stem, reaches the valve stem from ground level. There is no indicator on the valve assembly. |
