Product Description
Surface safety valve (SSV) is a hydraulically actuated fail-safe
gate valvefor producing or testing oil and gas wells with high
flow rates, high pressures, or the presence of H2S. The SSV is
used to quickly shut down the well upstream in the event of
overpressure, failure, a leak in downstream equipment, or any
other well emergency requiring an immediate shut down.
SSV is remotely operated by an emergency shutdown device (ESD),
which can be triggered automatically by high or low pressure
pilot actuators. If an emergency occurs, this feature reduces the
possibility of personnel injuries.
A number of SSV models are available for different well
conditions (pressures, temperatures, and flow rates) and with
various connections, such as hammer union or API*6A flanges.
All SSVs are manufactured under Type Approval or Design
Verification Review and provided with a Certificate of Conformity
and full quality file.
