Premium flapper valve for hostile environments and extended-life applications
Talk to an expertThe Halliburton NeoStar™ tubing retrievable safety valve (TRSV) is a premium, single-rod-piston, non-elastomer flapper valve for hostile environments and extended-life applications where ultimate reliability is required. The NeoStar TRSV builds on the legacy of the Halliburton SP™ TRSV platform by incorporating enhanced performance features that enable life of well reliability in subsea completions or hostile well environments.
The field-proven high-performance non-elastomer rod-piston seal system has been installed in over 12,000 Halliburton safety valves. It has been tested at 450°F and 25,000 psi (with gas) as zero-bubble throughout all static and dynamic scenarios. The rod-piston seal system achieves a full metal-to-metal (MTM) seal at its uppermost and lowermost positions to seal well pressure from the control system.
The NeoStar TRSV flapper/seat design features an embedded non-elastomer resilient seal for improved low-pressure sealing performance and maintains full MTM flapper/seat sealing capability for high pressure. The field-proven contoured flapper design improves OD/ID relationships, which allows for a wider range of applications and improved line bypass capabilities. A unique patented flapper closure mechanism eliminates coil springs to enhance debris tolerance.
The NeoStar TRSV quad-plane flapper hinge mechanism increases hinge system strength and improves closure mechanism reliability under harsh (high-rate) flapper closure scenarios.
The NeoStar TRSV sets the standard for premium, single control line, rod-piston TRSVs.
Helps to eliminate setting depth constraints, increase reliability, and reduce capex.
World’s first electric tubing-retrievable safety valve, enabling a fully electric completion system with zero risk of exposing electronics to wellbore fluid.
The Halliburton EquiStar® TRSV is a tubing pressure insensitive, non-equalizing, flapper-type safety valve that shuts down a well at a point below the surface.
