Abstract
A valve apparatus () for a flow system in a subsea oil and gas production installation and a method of use. The valve apparatus comprises an inlet for production flow from the subsea oil and gas production installation, an outlet for production flow, and a flow control valve () disposed between the inlet and the outlet. A first flow line () in communication with a sampling circuit is disposed between the inlet and the flow control valve, and a second flow line () in communication with a sampling circuit is disposed between the outlet and the flow control valve. The flow control valve is operable to be partially closed to create a pressure differential between the first and second flow lines, and thereby drive a production fluid into the sampling circuit.
