BNL has always been known as the "go-to" company for NavSea ball valves. The 803-5001003 is a highly versatile ball valve that has many applications in any marine environment.  Due to the reliability of the design, it is easily modified to meet requirements in any environment or market. 

Serviceability – The three-piece ball excels in applications where the end caps are welded or threaded in the pipeline.  The center section is easily removed from the line for servicing or replacement of parts, with no special tools. Entire center sections can be replaced in minutes getting your service back up and running.

Affordability – The three-piece ball valve is the economical alternative to gate and globe valves, both in initial cost and life cycle costs.  Furthermore, the high level of customization available with the 3-piece ball valve allows the valve to meet the process parameters, not the other way around.

Versatility –Ball valves may be used for on/off service, for limited throttling with standard trim, and more extensive throttling with special trim. Ball valves have low pressure drops and relatively high Cv, exceeding other traditional valve types.  Another advantage is the ability to have different end cap configurations, eliminating the need for pipe reducers/expanders and allowing for greater flexibility.

Reliability – Ball valves provide bubble-tight sealing with little-to-no upstream pressure and their ease of operation makes them a highly reliable option in even the most demanding of situations.  Ball valves are very predictable and have repeatable torque characteristics ensure years of trouble-free operation whether manually operated of actuated.
