Model TSV Tubing Retrievable Safety Valve
The Model TSV Tubing Retrievable Safety Valve is designed with a single rod piston and a non-elastomer seal flapper-type sub-surface safety mechanism, intended to shut off tubing well flow at a specified depth below the wellhead. The TSV safety valve is hydraulically controlled from the surface via a control line connected to the surface safety system control panel. In its default state, the valve is closed, with the closing force generated mechanically by a power spring. During production, the valve is held open by hydraulic pressure until this pressure is released from the control system.
The TSV safety valve is conveyed through tubing and features a metal-to-metal sealing body joint and closure mechanism. It includes a metal-to-metal sealing flapper and flapper seat combination to ensure optimal sealing performance. The actuating mechanism is equipped with a bi-directional, non-elastomeric seal stack to prevent gas migration through the hydraulic control line. Both self-equalizing and non-equalizing variations of the TSV Safety Valve are available.
The TSV valve is designed with an optional feature specifically for cementing operations. This feature prevents cement or debris from flowing into the flapper or actuator rod, ensuring that the integrity and functionality of the safety valve are maintained throughout the cementing process.
The standard operating parameters for the TSV safety valve feature a peak working pressure of 10,000 psi (68.9 MPa), suitable for a service temperature span from 68°F (20°C) to 177°F (350°C), contingent on the material grade used.
