Magnum Subsea Gate Valve

All Magnum Subsea Gate Valves are designed, manufactured, and tested to API 6A and 17G. Unique bi-directional sealing design provides a thru-conduit, upstream and downstream seal which creates a pressure-energized balance between the slab gate and seat assemblies when subjected to line pressure.

Specification and Features

Engineered to Surpass: T-slot stem and gate connection allows the gate to “float” between seats without misalignment of the stem under pressure. Centralized stem threads and t-nut combined with t-slot gate reduce the overall torque needed to cycle the valve

Unmatched Precision: Gate and seat faces are hard faced and polished to 1-2 RMS allowing for a positive metal-to-metal seal

Increased Service Life: Body cavity is exposed to line pressure only while the valve is being cycled, ensuring better lubricant retention, less exposure to line contaminants and longer service life with less maintenance
