MARS SERIES WIRELINE SAFETY VALVE
INTRODUCTION
The MARS series is a wireline retrievable surface controlled subsurface
safety valve that offers premium features similar to a tubing retrievable
safety valve. The MARS series are safety valves that can be supplied
with or without a self-equalizing feature. MARS series valves are
designed to be insert safety valves for tubing retrievable safety valves;
however, they can easily be adapted for use in a wireline nipple
completion. These wireline valves are premium valves due to the use of
non-elastomeric seal material, metal-to-metal housing threads, high
tensile strength metallurgy, and unique HP/HT packing and piston seal
stacks when required by the application. These design features are
imperative when considering applications for big bore, high temperature,
high pressure, extremely corrosive, and hostile.
FEATURES
• The flapper self-equalizing, most successful and widely used system
available to the market
• Two step metal-to-metal sealing system provides strength and sealing
under the harshest conditions.
• Large bore design, minimizes pressure drop and maximizes production
capability through the valve. Also, allows access for certain wireline tools
to be run through the valve, thereby saving downtime expenses normally
associated with pulling a wireline retrievable valve
• Rugged flapper construction, a large high strength alloy hinge pin
eliminates bending
