Because this ball valve’s stem and seals are encapsulated in a welded, sealed canister, if the seals fail, the transmitted medium cannot escape to the atmosphere. The valve is actuated by a magnetic coupling through the sealed canister, and uses a non-contact electromagnetic sensor to provide positive indication of the ball position. Previous valve designs were unable to provide an indication that the internal ball rotated to the desired open or closed position when the valve was actuated. The valves are available in a variety of construction and seal materials, with welded or flanged end connections.
