Subsea swing check valves are suitable in water depths
to 500 m (1700 ft) and maintain an average service life of 25 years. Available in both forged or cast materials, the design ensures total reliability for high pressure and high temperature services.
The swinging action of the disc away from the seat allows forward flow and when the flow is stopped, the disc returns to the seat, preventing backflow. Swing check valves are suitable for installations in lines where pigging operations are required for various maintenance services. The piggable design makes the swing check valve ideal for installation in riser pipelines and subsea applications.
Convenience of operation and simple in-line maintenance are essential features of our design. lnternal parts can be inspected and repaired without removing the valve off the pipeline even where space is restricted as in the top-entry trunnion ball valve construction.
The valve can be installed in both vertical and horizontal positions and offers unsurpassed quality and reliabilitywhile the simple design minimizes maintenance costs. Material selection is fully customizable to meet customers project specifications.
Axial, Piston and Swing Check Valves for Surface and Subsea Applications
Maverick’s Check Valve range supports client needs for a flexible approach to solutions where protection against back flow and pressure surges are concerned. The robust design of the Swing Check Valve is typically favoured to overcome these service conditions on large bore applications, whereas the Axial and Piston Check products provide assurance where a more compact design is demanded.
