His work has been instrumental in improving the efficiency and reliability of fluid control systems.
Latest Patents
Among his latest innovations is the "No-bleed pilot for pressure regulating valve." This control valve assembly features a no-bleed pilot valve that includes a pressure-responsive mechanism. This mechanism is designed to move in response to control parameters, such as downstream fluid pressure, allowing for selective connection of ports with upper and lower chambers of a control valve actuator. This design enables the actuator to operate effectively using both upstream and downstream fluid pressures.
Another significant patent is the "Elastomeric element valve." This fluid control valve incorporates a valve body, a cage, and a flexible elastomeric diaphragm. The diaphragm is uniquely designed with a formed convolution to fully open the cage opening. Additionally, it features a flow diverter in the fluid flow path, which reduces fluid flow separation and minimizes the required flow recovery area before pressure throttling. The valve also includes a raised knife-edge seat positioned to reduce the build-up of contaminants on the seat, enhancing the valve's longevity and performance.
