Hydrant valve with internal shut-off valve
A hydrant valve with an internal automatic shut-off valve. The internal valve blocks communication between a piston chamber and a hydrant chamber when in a closed position. An upper valve opens the internal valve against its biasing force permitting the flow of fluid between the hydrant chamber and the piston chamber. The internal valve closes in response to a disconnection of the upper valve.
