T-SERIES SUBSURFACE SAFETY VALVE

The T-Series Tubing-Retrievable Safety Valve is used in general production completion to shut in a well at a point below the surface. The valve contains a piston, opposed by a compression spring and the well pressure, which operates a flapper mechanism. When pressure is released from the piston chamber, the spring moves the piston up and the torsion spring rotates the flapper to the “closed” position. The simple compact design enhances the valve’s overall reliability while featuring an economical price.

Features and Benefit

• Simple, compact design

• flapper equalizing system

• It is highly reliable to use metal to metal sealing style in the sealing chamber

• Two step metal-to-metal sealing system provides strength and sealing under the harshest conditions

• Ultra strong power spring ensures smooth and reliable closures

• The optimized safety-valve design facilitates use of control-line communication and lockout tools to install a wireline-insert safety valve in the event of a malfunction, thus minimizing production disruptions

Application

• General production completions
