The Tejas FlowGATE™ tubing retrievable safety valves are rated for up to 10,000 psi [690 bar] working pressure and setting depths up to 2,000 ft [610 m].  They are available with premium piston hydraulic control line isolation and through-flapper, self-equalizing features.  FlowGATE™ valves are also available in ‘slimline’ and 'high-capacity' configurations for your most spatially constrained completion strategies.

​

The design approach for the FlowGATE™ safety valves was to remove as many hydraulic control system and flapper bypass leakage paths as possible to increase the operational reliability of the valves.  The resulting FlowGATE™ design has set the benchmark for the fewest hydraulic system and shut-in bypass leakage paths as well as total number of valve components in the industry.

​

In the unlikely event that the FlowGATE™ requires remediation, the Tejas Lock Open Tool (LOT) will permanently lock the flow tube in the ‘open’ position allowing for ‘full-bore’ thru-tubing operations.  Once the novel Tejas Communication Tool (COM) has been used to perforate the hydraulic piston bore, the FlowGATE™ safety valve is ready for the installation of the secondary, wireline retrievable safety valve.  The smaller internal FlowGARD™ safety valve can then be landed in the locked out and communicated tubing safety valve to meet regulatory safety valve compliance requirements and get the well producing again.
