Subsea Ball Valves

Reliable and Versatile Solutions for Harsh Environments

Maverick Valves Manufacturing specializes in subsea side-entry ball valves designed to excel in challenging underwater conditions. Our valves are engineered to operate effectively at water depths of up to 3000 m (10,000 ft) and boast an impressive average service life of 25 years. With a focus on reliability, safety, and durability, our subsea ball valves offer exceptional performance even under high-pressure conditions and in harsh environments with sand or solid particles.

Our subsea side-entry ball valves can be equipped with a subsea gear and ROV receptacle, enabling remote operation by a remotely operated vehicle (ROV). Alternatively, they can be configured with a handwheel for manual operation by a diver. To enhance functionality, valves can also be fitted with hydraulic subsea actuators, providing precise control in a double or single acting configuration. Additionally, some models offer the option for ROV override.

We understand that every application has unique requirements. That’s why our subsea ball valves are available in a wide range of materials and configurations, ensuring compatibility with various customer specifications and specific application needs. We prioritize customization to deliver the most effective solution for your subsea operations.
