Brighatech's NIRVANA Tubing-Retrievable Safety Valve (TRSV) is a flapper-type, equalizing or non-equalizing, surface controlled subsurface safety valve (SCSSV) installed in the production string. The valve is designed to provide subsurface isolation to minimize loss of production and protect the well. It also reduces the potential for environmental discharge or damage to production equipment resulting from an uncontrolled surface or subsurface event
The NIRVANA SCSSV is hydraulically controlled from the surface through a control line connected to the well control/emergency shutdown system.
Features:
- Hydraulically controlled.
- Single rod piston design.
- Maximized flow-through ID design.
- Self-equalized through flapper option.
- Non-elastomeric seals.
- Compact design and minimal number of parts increases reliability.
- Premium metallurgies and connections are available for varied environments upon request.
