TRC-II

Tubing-retrievable charged safety valve

Rated to 15,000 psi [103 MPa]
Rated to 300 degF [149 degC]
Validated to API Spec 14A V1 and V1-H

Maximize safety valve performance in deepset, low-operating pressure applications

The TRC-II tubing-retrievable, charged safety valve is a surface-controlled subsurface valve (SSV) that uses a gas-spring design with gas-powered actuators that allow installation at depths greater than 12,000 ft [3,658 m].

Because these valves can be run at greater depths, they can be positioned below the hydrate- or paraffin-deposit regions to increase operating efficiency.

Improve reliability with redundancy

The compact design of TRC-II valves incorporates rod piston actuators that are insensitive to tubing pressure and require substantially lower hydraulic operating pressures. Two separate piston systems connected to individual control lines provide complete operating redundancy. Either system is fully capable of operating the valve and incorporates a minimum number of critical, dynamic, and static seals; a 5-micron control fluid filter; and disconnect rod pistons to ensure fail-safe operation.

The valve features a rugged flapper-closure system and meets a leakage acceptance criterion substantially more stringent than API and ISO specifications.
