Latest Patents

One of Ralston's key inventions is a patent for a butterfly valve. This valve features improved inherent flow characteristics and dynamic torque characteristics. The design includes a disk that controls fluid flow within the valve. The disk is equipped with a sealing surface that interacts with a valve seal when in a closed position. The unique contour of the sealing surface creates a flow clearance as the disk pivots from closed to open. This design allows for a defined radius of curvature that characterizes flow through the valve at various disk positions. Additionally, the valve may include upstream indentations to reduce dynamic torque and accommodate fluid flow reversals.
