The FlowGARD™ is a wireline retrievable safety valve (WRSV) rated for working pressures of up to 10,000 psi [690 bar] and temperatures up to 300°F (149°C).  The FlowGARD™ compact design utilizes a GARD™ metal-to-metal ball and seat closure seal to provide 100% well containment when closed.

 

The FlowGARD™ is connected to a downhole lock and landed in either a dedicated hydraulic landing nipple or inside a TRSV where hydraulic communication has been established. The FlowGARD™ operates with a surface-controlled emergency shutdown (ESD) system that supplies hydraulic control pressure to actuate the hydraulic piston to open the ball and seat closure mechanism.  The FlowGARD™ is a “fail-safe”, normally closed valve that will protect production installations from uncontrolled flow if wellhead equipment is damaged in a catastrophic event.

 

After shut-ins, the integrated self-equalizing design facilitates a rapid return to production, reducing operational downtime.  The FlowGARD™ is tested/certified to API-14A-Grade V1 and manufactured in accordance with API-Q1 and ISO-9001:2015 standards.  Materials selection options are based on NACE MR-0175 compliance.
