SCHWERLL’s official product listing identifies a series of large-bore high-pressure ball valves with a shut-off function. This page represents the product family, rather than a single supplied manufacturer part number.
Published manual-lever capability example
The official SCHWERLL listing describes manual-lever opening and closing at a DN125 nominal size and a 35 MPa pressure condition. This is a published combination and capability example. The source does not identify DN125 as the series maximum size or 35 MPa as a series maximum, universal working pressure or design pressure.
The DN125 and 35 MPa values belong together in this example. They must not be converted into independent size and pressure ranges for every ball valve in the series. No additional size range, higher-pressure series or operating-torque value is asserted here.
The manufacturer describes the family as providing reliable shut-off and describes manual operation at the published combination. Confirm the permissible conditions, selected valve and operating procedure against approved documentation before opening or closing the supplied valve; this listing does not establish a universal safe-operation guarantee.
Before ordering or operation, confirm the supplied model, nominal size, allowable pressure and its definition, actuation, interfaces, materials, medium compatibility, operating temperature and applicable inspection or conformity documentation. Requested variants, availability and delivery dates require written confirmation.
