Magnum Subsea Dual Block Gate Valve

Specification and Features

  • Dual Seal Technology: 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
  • Surpassing Industry Standards: WOM’s Horizontal Subsea Trees feature horizontally-positioned primary valves allows for easy access for tubing retrieval and workover intervention operations, without requiring the tree to be removed
  • World-Class 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


The Magnum Subsea Gate Valve is available in a Dual Block configuration in sizes up to 7 1/16″ and in working pressures up to 20,000 psi.
