Abstract
An apparatus includes a valve having a hollow body and an inner sealing assembly positioned in the hollow body. The inner sealing assembly includes a piston and can be moved between an open position and a closed position to selectively control flow along a flow path through the valve. The flow path includes a bore of the piston that allows flow through the piston, and pressure within the valve from a fluid in the flow path within the valve biases the inner sealing assembly toward the closed position to stop flow through the valve. Additional systems, devices, and methods are also disclosed.
