Sterlco R-152-F Steam Pressure Reducing Regulator

The Sterlco R-152-F is a self-modulating temperature regulating valve for steam service that automatically modulates downstream steam flow to help maintain a target outlet temperature, making it a precise control valve choice in boiler rooms and process heating loops. Part of Sterlco's line of temperature control valves, the R‑152‑F embodies the brand’s self-modulating design that helps maintain temperature, flow, and pressure in steam systems. Common applications include heat exchangers, direct steam heating, and steam-to-water service, with Sterlco brochures illustrating uses such as blowdown separators and heat exchangers. Industry listings indicate a temperature-setpoint range that varies by model, commonly shown as 85–125°F or 105–145°F, and the unit weighs about 3.03 lb. Manufactured by Sterlco, the R-152-F is a valve component used where precise steam temperature control is required in heating or processing environments.
