Function:Dual-Activation System:
Hydraulic Activation: Employs rig hydraulic power to achieve a complete seal in less than 3 seconds, facilitating swift emergency responses in the face of sudden wellbore pressure spikes.
Mechanical Redundancy: Features a manual override option (via hand pump or wrench-operated backup), ensuring continued functionality even if the hydraulic system fails.

Pressure Integrity:
Rated for a working pressure range of 10,000-15,000 psi (adjustable to suit specific applications), complemented by a 1.5:1 to 2:1 safety margin, fully compliant with API Spec 16A.
Built from high-strength alloy steel (such as 4140/4145), meticulously heat-treated for uniform hardness (HRC 26-34) and NACE MR0175 compliance, suitable for sour service environments.
Advanced Sealing Mechanism:
Primary Metal Seal: Features tungsten carbide or stellite-coated sealing surfaces, designed to withstand erosion from abrasive drilling fluids and high-velocity particulates.
Secondary Elastomeric Seals: Composed of high-performance polymers (e.g., HNBR, FFKM) rated for temperatures ranging from -30°C to 200°C (-22°F to 392°F), ensuring dependability in extreme conditions.
Flow Efficiency:
A full-bore design (ID 3-1/2″ to 7-1/16″) minimizes flow restrictions, thereby maintaining optimal mud circulation rates.
Anti-swab/surge geometry is strategically designed to reduce pressure fluctuations during tripping and connections.
Operational Benefits
Rapid Well Control:
Seamlessly integrates with rig BOP systems to instantly isolate the drill string, effectively mitigating the risk of kick escalation.
