Isolation valve with thermometer

The Legend Valve 833-855 is a 1-inch isolation valve with an integrated thermometer designed for industrial piping systems. It connects via FNPT x NST threads and is finished in red for clear identification. This new component provides flow control and temperature monitoring within a single fitting.

Integrated temperature measurement

The built-in thermometer allows operators to read system temperature directly at the valve without installing a separate gauge. This accessory-style connection simplifies piping layouts and reduces potential leak points. The stainless steel construction suits the specified operational conditions for which the valve is rated.

For maintenance and process lines

This valve suits technicians who need combined isolation and temperature verification in 1-inch piping. It is not intended for applications requiring different connection types, larger nominal sizes, or separate temperature ports. Buyers needing alternative thread standards or valve configurations should look elsewhere.

Questions about this item

Does the integrated thermometer on the 833-855 valve need periodic recalibration?

The thermometer is built into the valve body for continuous temperature reading; no separate calibration procedure is detailed by the manufacturer.

What temperature limit does the 833-855 assembly reach first during constant flow?

The valve body and thermometer share the same system temperature rating, so the fluid temperature limit is the first boundary reached under sustained operation.

How much heat does the 833-855 valve radiate when left in an open-loop system all day?

The valve itself adds no active heat; it simply conducts the fluid temperature, so radiated heat matches the pipe surface temperature.
