MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202617075409 A) filed by Velan Inc. on June 18, 2026, for Top-Entry Ball Valve With Pressure Seal Bonnet For Power And Nuclear Applications.
Inventors include Lourdel, Nicolas Herv Franois; Paquin, Michel Sylvain Mario; Major, Paul; Patel, Ashit Mukeshbhai Number; El Yacoubi El Idrissi, Zakaria Mohamed; and Jacobs, Michael Joseph.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: A compact and lightweight two-piece valve shell (body and pressure seal bonnet) structure reduces possible leakage paths while also providing a top-side ball/stem installation/removal path (when the bonnet piece is not present) to facilitate initial valve assembly as well as subsequent inspection/removal of the ball/stem and other valve internals for conducting valve maintenance without requiring the valve body to be removed from its process connections and without removing the bracket and actuator. Sealing seats can be adjusted in overall length using fluid, vacuum, threads or cams to ease the assembly of the ball inside the body. The sealing seat adjustment can be completed with the ball inside or outside the body cavity.
