Subsea gate valve
Our MCS subsea gate valve is a compact valve suited for the rugged requirements of subsea choke-and-kill lines in water depths up to 10,000 ft.
The valve is hydraulically actuated. The detachable actuator requires only 5 in of clearance for removal without requiring removal of the valve from the line. The bonnet, packings, and stem remain in the valve when the actuator is removed.
A balanced stem prevents fluid displacement and prevents opening when line pressure is less than sea pressure. The exposed balancing stem allows visual indication of gate position. Bidirectional sealing allows valves to be spaced closely without liquid lock.
The one-piece seats and slab gate minimize cavity parts, which simplifies maintenance.
