APPLICATIONS ■ Testing oil and gas wells with high flow
rates, high wellhead pressures, or the
presence of H2S
■ Wells with hazard operational analysis
needing a surface pressure barrier in
addition to the primary or master valve
BENEFITS ■ Prevent overpressure conditions
on downstream equipment
■ Provide immediate well closure in the
event of downstream equipment failure
■ Ensure reliable shut-in during harsh
environment operations
■ Reduce personnel exposure
in emergencies
■ Comply with environmental regulations
and reduce environmental risk
FEATURES ■ Fail-safe remote activation and auto-
matic well closure when loss of control
pressure occurs
■ Double metal-to-metal seals for
reliability in harsh environments
■ Normally equipped with hammer
unions, but can be fitted with Grayloc®
or API-6A flanges
■ Compliance with API-6A (PSL-2 or 3,
PR2), H2S (NACE MR0175), and
Fluid Class DD specifications
The surface safety valve (SSV) is a hydraulically actuated fail-safe gate valve for testing oil and
gas wells with high flow rates (>8,000 bbl/d [>1,280 m3 /d] or 30,000,000 ft3 /d [>850,000 m3 /d]), high
pressures (>5,000 psi [>34 MPa]), or the presence of H2S. The SSV is used to quickly shut in
the well choke manifold upstream in the event of overpressure, failure, a leak in downstream
equipment, or any other well emergency requiring an immediate shut-in.
The 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 Grayloc or API-6A flanges. All SSVmodels have interchangeable crossover connections and are protected by a compact,
removable lifting frame.
The SSV uses a proven metal-to-metal, double-sealing design for harsh environment operations
and complies with all applicable environmental requirements. All SSVs are manufactured under
Type Approval or Design Verification Review and provided with a Certificate of Conformity and
full quality file.
