Isolation valve with thermometer

The Legend Valve 833-825B is a stainless steel isolation valve with an integrated thermometer for system monitoring. It fits 1-inch FNPT x NST piping configurations in industrial and commercial installations. The valve provides reliable flow control for maintenance or shutdown procedures. Buyers needing larger diameters or different connection standards should look elsewhere.

1-inch rated flow control

This valve is rated for 1-inch piping systems and delivers isolation within specified pressure and temperature ranges. The built-in thermometer allows direct temperature measurement without additional instrumentation. It handles standard industrial flow demands but is not suited for oversized mains or high-capacity distribution headers. California Proposition 65 warnings apply to materials used in this product.

Stainless steel construction thermals

Stainless steel body resists corrosion and maintains integrity across the rated operating envelope. No external power or moving cooling parts are involved, so operation is silent and draws no energy. The thermometer reads system temperature passively during normal flow conditions. Installers should verify compatibility with the specific media and pressure parameters of their application.

Questions about this item

Will the 1-inch FNPT threads on this 833-825B valve match the NPT fittings already on my older copper piping?

The valve uses 1-inch FNPT threads, the standard taper pipe thread in North America, so it will mate with existing 1-inch NPT male fittings on copper, steel or brass pipe without adapters.

How can I verify the built-in thermometer is reading correctly once the valve is installed and pressurised?

Compare the thermometer reading against a calibrated reference thermometer placed in the same fluid stream; the gauge should track within its marked tolerance when the system reaches steady temperature.

Does the 833-825B come with the thermometer already fitted, or do I need to buy a separate gauge and thread it in?

The thermometer is included and pre-installed in the valve body, so no separate gauge purchase or additional threading is required.
