Ball valves offer a compact solution for many of the design demands associated with subsea applications.
Typically the ball valve options would be suitable for high flow applications to water depths of 3000 meters.
BEL Valves design an extensive range of qualified ball valves in bore sizes from 1 to 28 inch with end or top entry configurations.
They feature patented metal-to metal sealing, single or double piston effect seats and are available in a range of materials including duplex, super duplex and Inconel.
Qualifications include PR2, hyperbaric, 1200 cycle and sand slurry testing. The range includes large bore, tight shut off, double block and bleed type valves.
Typical applications might include subsea isolation valves and emergency shutdown valves and for isolation duties on manifold export and flow lines.
