The valve includes a body having a longitudinal flow path, a valve seat detachably mounted in the upper portion of the body and opposed flapper plates which seat against each other to close the valve or are rotated downwardly by actuator shafts to open the valve. The flapper plates define adjacent edges which seat against each other by a sliding action permitted by movement of one of the two actuator arms.
