Trerice 91400USNTC01 Regulator Valve

The TRERICE 91400 USNTC01 regulator valve is a self-contained temperature regulator that automatically maintains process temperatures for liquids, steam, and other media without any external power source in industrial heating, cooling, and process-control systems. It includes an integral indicating dial for local temperature monitoring and adjustment, housed in a die-cast aluminum enclosure with an epoxy-coated finish, and it uses high-pressure brass bellows tin-plated for durability. The valve supports single-seat, double-seat, and 3-way valve bodies and offers overrange protection of +100°F above the upper control point under temporary conditions. Common applications span industrial heating, steam distribution, commercial HVAC, and process industries such as food and beverage processing and chemical manufacturing, and it is a recognized replacement option alongside TRERICE 91000, 91600, and Spirax Sarco 25P.
