NOV sets a new standard for SSSVs

06 July 2018

NOV has partnered with Tejas Research & Engineering to commercialize a new line of subsurface safety valves (SSSVs). The new valves meet the rigorous standards set forth in API Specification 14A and are tested beyond the HPHT specifications of Annex H.

The new surface-controlled, tubing-retrievable SSSVs are rated for working pressures up to 10,000 psi (68 948 kPa) and temperatures up to 300°F (149°C). The valves use a non-elastomeric, single-piston actuator, optional self-equalizing flapper, and metal-to-metal flapper closure seal to provide 100% well containment when closed. NOV 2⅞-in. safety valves are available now, and additional sizes are forthcoming.
