  • Gate valve with delayed retraction of counter plate
    Patent number: 6612546
    Abstract: A valve, such as a gate valve, includes a housing having a fluid conduit and defining a valve seat and a support surface, a seal plate, a counter plate, an actuator for moving the seal plate and the counter plate between an open position and a closed position, and a coupling mechanism operatively coupled between the seal plate, the counter plate, and the actuator. The seal plate is in sealed engagement with the valve seat, and the counter plate is in engagement with the support surface in the closed position. The coupling mechanism retracts the counter plate from the support surface subsequent to retraction of the seal plate from the valve seat as the valve is opened.
