Butterfly valves use flat, circular discs that pivot in the center of pipes to regulate fluid flow by means of a quarter-turn motion. Butterfly valves are popular in a variety of applications due to their relatively simple design and usage. They have slim face-to-face dimensions and are excellent at sealing. As quarter-turn valves, they are also easier to actuate. They can be operated with levers, gear operators, or actuators.

A lugged connection is a type of connection where the valve body has threaded lugs (or ears) that align with the bolt holes of joining flanges. Unlike a wafer-style connection, adjoining flanges get bolted directly into the body of the valve. This design allows for sections of pipeline to be removed on one side while keeping the valve connected on the other side - simplifying repairs.

Bronze is an alloy of copper and tin - often combined with additional elements to change the properties of the component material. It is durable, resistant to corrosion, and has a high melting point. Bronze is a highly versatile material utilized in many contexts including marine and seawater applications.
