Double Ball Marine Hull Valve

Double Ball Hull Valve is engineered for extreme marine conditions, providing superior safety, corrosion resistance, and ease of maintenance. Designed with two trunnion-mounted balls for redundancy, it ensures secure isolation in critical applications. The valve features a top-entry design for in-line maintenance, reducing downtime and costs. Constructed from high-performance materials such as Nickel Aluminium Bronze, Inconel, Titanium, and Monel, it offers excellent resistance to biofouling and harsh environments. With a manual override for emergency operation, this valve is ideal for submarines, cooling systems, and seawater applications requiring reliable isolation under demanding conditions.
