Patent number: 12140233Abstract: A new and innovative high-pressure priming valve is provided for use in high-pressure fluid systems that require a high level of fluid purity. The priming valve includes at least three ports, some of which are angled. The priming valve also includes a needle that variably blocks and unblocks a pathway to one of the ports between normal operation and a priming operation, respectively. The priming valve includes a sealing insert positioned below a stack of washers that maintain the needle's alignment in response to high fluid pressures exerted on the needle. The sealing insert helps prevent fluid from contacting the stack of washers, which helps prevent biological growth within the valve. The angled ports help facilitate priming valve drainage to further help prevent biological growth. By helping prevent biological growth, the sealing insert helps prevent fluid contamination and enables the priming valve to be utilized for high-purity fluid applications.Type: GrantFiled: December 2, 2022Date of Patent: November 12, 2024Assignee: IDEX MPT INC.Inventors: Rachel Otte, Ahmad Shehata, Jocemar Ramina, Marco Catalani, David Harney, John Michael Bernard, Michael Ratigan, Harshit Kumar Patel

Publication number: 20210190052Abstract: The present application provides new and innovative high-pressure fluid systems for preventing seal burning due to gas auto-ignition. The provided systems include an o-ring disposed within a seal cavity of a cup seal to decrease the dead volume in the seal cavity. By reducing the dead volume, the o-ring decreases the volume of gas that is able to accumulate and thus helps prevent the gas from auto-igniting as the gas is compressed. By preventing the gas from auto-igniting, the provided system helps prevent seal burning, which helps prevent premature cup seal failure and prevent fluid contamination.Type: ApplicationFiled: December 18, 2020Publication date: June 24, 2021Applicant: MICROFLUIDICS INTERNATIONAL CORPORATIONInventors: Yang SU, John Michael Bernard, Marco Catalani, David Harney, Jocemar Ramina, Michael Ratigan
