GESTRA Calorimat Return-Temperature Control Valve, BW31

GESTRA’s BW 31 return temperature limiter (Kalorimat) adjusts consumption in industrial heating systems based on demand, boosting medium flow in the return line as temperature decreases. Flow only occurs when the medium’s temperature falls below the set closing threshold. Utilizing a thermovit regulator and spring pressure, the BW31 manages medium flow and is primarily designed for hot water applications.
