Latest Patents

One of his latest patents is the "Ported slide gate valve with gate motion to break scale build up." This invention features a gate that regulates fluid flow through the valve and includes a mechanism that fractures scale buildup in the valve's lower portion before the gate closes. The design incorporates a primary piston coupled to the gate and a secondary piston that holds the primary piston in place when the valve is closed. This innovative approach ensures that scale is directed away from the seat and into the fluid.

Another significant patent is the "Trunnion type ball valve," which is designed to eliminate the need for biasing means to establish a seal between the valve seats and the ball when closed. This valve allows for no load on the seats when open and sufficient load when closed to create a fluid seal. The valve seats are movably mounted, allowing them to center themselves during operation.
