Technology

WOM’s Magnum Gate Valve provides sealing reliability that is unmatched in the industry.
The patented design has been proven in hundreds of well control applications during drilling,
testing, production, in onshore, offshore and subsea.

The key to Magnum’s superior bi-directional sealing is the “Dual-Seal™” system. This unique
“Thru-Conduit” design provides both upstream and downstream sealing, creating pres-
sure-energized balance between the slab gate and the seat assemblies. The “Dual-Seal™”
seats expand against the gate when subject to line pressure to form a positive
metal-to-metal seal.

The body cavity is exposed to line pressure only during valve opening and closing, ensuring
better lubricant retention, less exposure to line contaminants and longer service life with less
maintenance.

• API pressure ratings of 2,000 to 20,000 psi
• Full Bore, Through-Conduit Seal
• Bi-Directional Sealing
• Primary (Upstream) Seal
• Secondary (Downstream) Seal
• Lower Torque
• Floating Gate with T-Slot
• Centralized stem threads
• Superior finish on gates and seats
• Balanced forces on gate and seats
• Longer Life of Gate and Seals
• Minimal exposure to contaminants
• Minimal lubricant loss
• Elastomer Assist Metal-to-Metal Seal or
Non-Elastomeric Seals

Maintenance Requirements

Elastomeric &
T-SLOT GATE BENEFITS Non-Elastomeric Seals

Low Torque
An independent stem nut allows the gate
to maintaining contact with the
seats without binding on the stem. Better
retention of lubricant in the body cavity
reduces build-up of contaminants which
can increase torque.
