TRFC-HN Single-Line, Multiposition Flow Control Valve

Overview Library

Interval control valve with built-in nitrogen chamber to provide the closing force and minimize well penetrations

The surface-actuated, tubing-retrievable TRFC-HN single-line flow control valve uses one dedicated hydraulic control line to activate the choke section and control flow in producing wells. Applying hydraulic pressure to the control line actuates the valve, and a gas spring returns it to the original position when the pressure is bled off, minimizing well interventions. The multiposition valve can be supplied in on-off, three-, four-, seven-, or eleven-position configurations. The main advantage of these configurations is to enable multidropping of more valves on fewer control lines.

Wide range of applications

Rated to 7,500 psi [51.7 MPa] and 325 degF [163 degC], these interval control valves are manufactured in a variety of materials, all meeting NACE specification MR0175. The rugged design makes the valve suitable for severe environments with scale deposits, erosion, and other demanding conditions.

Nozzle-design flow ports ensure well-defined flow characteristics for the various choke positions and minimal erosion at high differential pressures. WellWatcher permanent monitoring systems can be deployed in conjunction with these valves to monitor downhole pressure and temperature for a better understanding and more precise control of the reservoir in real time.

Control of annular or inline flow

Two versions of the TRFC-HN valve are available—annular and inline. The annular valve controls flow between the tubing and the annulus. The inline valve controls flow inside the tubing via a shroud across the choke section and a retrievable plug installed immediately below the choke section. Flow is diverted by the plug into the shroud and reenters the tubing through the choke.
