Fisher Relief Backpressure Pilot Operated LR128 Or Pressure Valve Regulator

The 'LR' prefix on LR128 denotes an alphabetical series identifier adopted by Fisher to group related valve variants by size, rating, or connection style. Fisher engineering practice emphasizes tight tolerances and conservative ratings, qualities that make its valve line suitable for demanding installations.

Fisher supplies the LR128 as part of its industrial valve portfolio; the unit is specified where sealing class, flow coefficient, and pressure rating must match the surrounding process envelope.

This valve is applied in pressure relief on compressed-air headers, flow regulation in water-treatment loops, and emergency shut-off on steam lines, with manufacturing being a frequent deployment context.
