Prevents backspin of ESP
Failsafe closed
Metal to metal valve seat and poppet design for reliability
Pump-thru/equalisation capability

Pros & Limitations

FLV operation prevents backspin of ESP

Metal to metal valve seat and poppet design for reliability

Precision burst disc for pump-thru/ equalisation

Standalone unit can be adapted to suit a variety of deployment scenarios

Subsurface controlled design requiring no hydraulic or electrical power to operate

Specification

Specification Title	Specification Description
Areas of Application	Retrofitting of safety valve in any well \| Rigless cable-deployed ESP systems \| Jet pumps and velocity strings \| Coil tubing deployed ESPs.
Pressure	Patent pending design allows bi-directional sealing up to 5,000 psi. Well pressure or surface test pressure boosts valve shut.
Engineering Tools	SP Latch: facilitates positive location of the SPSV into a packer seal bore and prevents pump out \| SP Packer: Designed specifically for the SPSV for simplified deployment.
Deployment	The SPSV can be run on cable or wireline independently, as part of the ESP assembly or as part of the packer assembly.
Certifications / licenses	150c rated to API 14A V3 12th Edition.
