Industrial TRERICE-20-70F-2NPT Ambient Temperature Regulating Valve

The TRERICE-20-70F-2NPT Ambient Temperature Regulating Valve is a self-operating, power-free regulator that automatically maintains process temperatures in the 20–70°F range. Designed for industrial cooling water systems, heat exchangers, HVAC equipment, process piping, storage tanks, and machinery, it modulates valve position via a thermal sensing system without electrical or pneumatic power. Specifications include a 2 in. NPT threaded connection, ambient temperature regulation, and a valve body available in bronze, cast iron, steel, or stainless steel depending on configuration; temperature range 20–70°F (-10 to 20°C). Common replacements are TRERICE 91000, TRERICE 91400, and TRERICE 91600.
